MICROMETER MEASURES OF DOUBLE STARS IN 2015Bob Argyle, Lyndhurst, Ely Road, Waterbea h, Cambridge, CB25 9NW, UKE-mail: rwa�ast. am.a .ukIntrodu tionIn this publi ation, the author presents his mi rometri measurements whi h were mostly madebetween 2015.0 and 2016.0. A small number of pairs have mean epo hs outside this range either dueto delay in getting a su� ient number of observations to form a mean, or whi h were inadvertentlyleft out of earlier papers. The 8-in h f/14 Cooke refra tor at the Observatories of the Universityof Cambridge has again been used for this work. It is equipped with a RETEL mi rometer at apower of x450. Using a Barlow lens, the s rew onstant is 12′′.45 per revolution whi h allows anequivalent reading a ura y of ±0′′.025. The s ale and orientation of the mi rometer is derived atthe beginning and end of ea h observing session using a number of �xed, wide pairs with astrometryfrom the Hippar os satellite.Measurements are arranged as usual (see Courtot & Argyle, 2004 for more details). Table 1gives the name of the pairs using the WDS nomen lature2 with the following odes and ontains293 measurements of 86 systems:AC Clark, A. C. BU Burnham, S. W. SHJ South & Hers helD Dembowski, E.

AppendixThe proto ols followed here for measuring are very similar to earlier publi ations and onsistbasi ally of multiple double measures of separation (usually 4 or 5) and repeated measures ofposition angle (usually 4 to 6) taken on several di�erent evenings taken together to get the �nalmean values of position angle and angular distan e.Table 3 gives the residuals from known orbits.

MICROMETRIC MEASURES OF DOUBLE STARS IN 2015Jean-François Courtot, Chaumont, Fran eIntrodu tionThe measurements presented here have been made during 2015 using a homemade 205-mm Newto-nian. Most measurements have been obtained using a Lyot double-image mi rometer (L) althougha Retel �lar mi rometer (F) or a hronometri method (TM, Transit Method) have also been usedon some o asions. The pro edures have been outlined in a previous DSSC1.Attention has been paid in this series to some pe uliarities of the birefringent double-imagemi rometer. The �gures below show what it is about.

Figure 1: Typi al distortions observable with a double-image birefringent mi rometer under spe i� atmospheri onditionsDis ussionUnder spe i� atmospheri ir umstan es a di�erential shift e�e t in apparent position angles anbe observed with this kind of mi rometer. This e�e t has been previously des ribed notably bythe late Danish astronomer Niels Wieth-Knudsen2 using a Müller quartz glass rystal mi rometer.This e�e t an be observed with the birefringent Lyot mi rometer as well.On the upper line of the �gure, suppose AB is the ordinary image of a pair and A'B', theextraordinary image in the double distan e on�guration, Wieth-Knudsen observed that bothimages may `'dan e� around their mean position in opposite dire tions: �ea h one of the twodi�erently polarized images has its own dan e�. Although not permanent, it has been more oftenthan not possible to learly observe this e�e t. On some o asion, under very alm seeing andhigh stable summer temperatures, it has also been observed that the four images A, B, A′, B′ ouldnot be aligned at all for long se onds, the images being very stable - not �dan ing� - but showingdi�ering position angles. This di�eren e in apparent position angles for AB and A'B' an amount toseveral degrees. When this o urs, the observer has to stop measuring or try to �nd an intermediatesetting as shown on the upper line on the �gure.It has been observed also that onditions may a�e t di�erently, durably or sporadi ally, notonly the apparent position angles but also the apparent distan es between the omponents in theordinary and the extraordinary images. This e�e t is more apparent for the wider pairs. Forinstan e, as shown on the lower line of the �gure, at a given time, A'B' may look loser that AB,leading to the impossibility of setting the spath blade in lination so that B A′= AB = A′B′asusual. Both e�e ts may appear in the same time.6

It happens also that both ordinary and extraordinary images do not show exa tly the samebrightness. All these pe uliarities observed with a birefringent double image mi rometer dependon lo al atmospheri onditions. With this kind of mi rometer, the ordinary and extraordinaryimages are linearly polarized with a 90◦ di�eren e. This suggests that the observed e�e ts haveto be asso iated with a temporary partial polarisation of the in oming light from the stars troughthe atmosphere behaving as an unstable �multirefringent� medium; the spath blade a ting thenas an opti al analyser. As reported before, all these e�e ts may be observed not only under fastmoving unstable onditions but also under very alm seeing as well. In this ase, the e�e ts arejust slowed down and at time steady, like �frozen� for several se onds.If identi�ed when they o ur, the above des ribed e�e ts are usually not of real trouble sin e,with some pra ti e, satisfying intermediate settings an be found for both position angle ir leand spath blade in lination. This may however look at �rst like a drawba k for the birefringentdouble image mi rometers but in fa t this kind of mi rometer helps the observer to be aware indue time of what is happening with the images he is observing. A �single-image� mi rometer willnot ne essarily do it, espe ially when slow rate or �frozen� image distortion o urs (3).Measurements have been arranged as usual in Table 1.

MEASUREMENT OF DOUBLE STARS AT THE WINEROBSERVATORY AND DISCOVERY OF NEW PAIRSAndre Deba kére, Double Star Commission, So iété Astronomique de Fran eE-mail: andre.deba kere�free.frAbstra tDuring 1996, whilst I was working on the identi� ation of double stars to be part of the CCDM atalogue, I dis overed three new ouples in Andromeda subsequently alled DBR 1, DBR 2 andDBR 3 with my own Newtonian teles ope (T 207/1351 mm).In late 2004, I was able to use a 14-in h S hmidt Cassegrain teles ope (Celestron C14) �ttedwith a SBIG ST 8 CCD amera thanks to Thierry Lépine, Professor at the Opti al GraduateS hool of Saint-Etienne, Fran e. The exploitation of the images obtained with this teles ope atthe time of my 2004 and 2005 observations, enabled me to dis over 9 new pairs from DBR 6 toDBR 14. DBR 4 and DBR 5 are not registered in the Washington Double Stars atalog (WDS1).Introdu tionIn early 2015, I used the roboti teles ope Rigel2 thanks to Robert Mutel, Professor of Astronomyat the University of Iowa to remeasure the double stars that I dis overed about 10 years previously.Among these ouples were the named pairs DBR6 and DBR7 that I measured in 2005. I presentthe measurements of these pairs here along with notes on the dis overy of �ve new ouples usingthis venerable teles ope (now repla ed by the Gemini teles ope, a f/6.8 Cassegrain re�e tor witha 0.51-m primary mirror).Reminder : To measure a double star is to determine two polar oordinates alled: position angleθ (in degrees ounted from the dire tion of north and turning east) separation ρ (in ar se onds).

Figure 1: The A and B omponents of a double star in the astrometri oordinate system and the polar oordinates θ and ρ.MethodTo determine these polar oordinates one an establish a list of referen e pairs from the measure-ments made by the Hippar os satellite and for whi h the angular distan e (separation) hanges11

little over time, and whi h one an model the evolution of the position angle. However, the use ofthese referen es showed that position angle and separation predi tions are not always satisfa tory.I measured the pre ise equatorial oordinates (right as ension α and de lination δ) of ea h omponent usingAstrometri a3 software and using the UCAC atalog4 to al ulate the positionangle and the separation with good a ura y.In Fig. 1, the three sides of the ABH triangle are ir ular ar s, not straight segments. The al ulation below does not work for larger angular distan es but only for small angular distan es(when the tangent is very lose to the value of the angle in radians) we an onsider the ABHtriangle as a right triangle in H and then we an apply Pythagoras' theorem.∆X(◦) = 15 × (αA − αB) × cos(δA) (with α measured in hours)and

∆Y (◦) = (δA − δB)thenρ =

√

(∆(Y )2) + ∆(X)2)

θ = arctan(δA − δB)

(αA − αB)The value of θ depends on the position of the omponent B in the �eld as an be seen in Fig 2.

Figure 2: The �eld is divided into 4 quadrants, Nf : North following, Sf : South following,Sp : South pre eding and Np : North pre eding.From these al ulations we an determine the position angle θ and the separation ρ of thereferen e pairs to the date of observation. The main di� ulty in measuring a double star lies inthe alibration of the CCD image. We must know with a uren y : the orientation ∆ (in degrees)of the sensor relative to the diurnal motion (E-W), and the sampling, or pixel size, S in ar se ondsper pixel of the digital image.A quiring imagesTo obtain images with a roboti teles ope, the observation request on the Internet must in ludethe name of the target, its J2000 oordinates, the exposure time and sele ted �lters, the number12

of images, the date of observation, and so on. When the images are ready you are informed bye-mail and you an download them.The teles ope used was the Rigel roboti teles ope at the Winer Observatory in Sonoita, Ari-zona. This is operated by the University of Iowa and is a 37- m f/14 lassi al Cassegrain system onan equatorial fork mount. The imaging amera is a Finger Lakes Instruments (FLI) Proline CCD amera with a Kodak 16803 front-illuminated sensor ooled to -35◦ C. The sensor has 4096 x 4096(16M) 9-mi ron pixels giving a �eld of view is 25′ x 25′ with a plate s ale 0′′.73 per pixel using2× 2 pixel binning. This gives a resultant fo al length of 5080 mm. The sensor has a maximumspe tral response between 500 and 600 nm. The images were taken without �lter.Date : February 18, 22 and Mar h 14, 22, 2015Site : Winer Observatory, Sonoita, AZ, USA1) Images entered on RA = 06h 27m 18s.00 and DEC = +24◦ 30′ 00′′.0a) Addition of 11 images, aligned and sta ked with IRIS5 software.

We an more easily dete t tight doublestars. This image shows three new pairs. However we an not measure these ouples ex ept withdi� ulty, the number 2 be ause the sampling is too large. These ouples will be subsequentlymeasured using teles opes giving a ess to separations lower than 3 ar se onds.16

Are these ouples ofstars whose small opti al separation is only asual or are they on the ontrary physi al oupleswhose omponents obey the laws of gravity as William Hers hel was the �rst to think about it?Large separation physi al ouples have very slow orbital movement and it an take thousands ofyears to omplete an orbit, but they are nevertheless identi�ed by their ommon proper motion.Table 4: Mean measures from observations in this paperWDS Name Cat.Name RA(2000) De (2000) VA , VB Obs date θ ρ Nights(2015+) (n)06224+2646 DBR 16 06:22:38.73 +26:46:42.1 13.0, 15.4 0.14 303.2 2.96 106271+2428 DBR 4 BC 06:27:08.52 +24:28:39.0 12.6, 13.4 0.13 74.1 4.03 106271+2428 POU 1332* 06:27:09.49 +24:28:26.5 12.1, 12.6 0.14 323.6 15.54 206273+2427 POU 1333 06:27:18.13 +24:27:05.1 10.9, 12.3 0.14 289.6 11.03 206273+2430 POU 1334 06:27:19.11 +24:30:47.9 13.6, 14.2 0.14 354.2 9.04 206274+2430 DBR 6 06:27:26.84 +24:31:52.8 13.6, 14.2 0.13 163.8 7.18 106275+2432 AG 112 06:27:30.03 +24:32:00.8 9.8, 9.9 0.14 209.0 2.84 206275+2432 OPI 12 06:27:30.03 +24:32:00.8 9.8, 11.4 0.14 338.6 42.76 206275+2436 POU 1337 06:27:34.93 +24:36:28.9 11.9, 13.2 0.14 140.5 16.94 209316+2124 DBR 5 09:31:55.09 +21:24:57.2 12.0, 12.5 0.21 283.9 2.71 209324+2129 DBR 7 09:32:21.97 +21:28:36.6 15.1, 16.0 0.21 104.8 3.78 2

DISCOVERIES OF NEW PAIRS WITH THE LCOGT NETWORKTELESCOPES (T2M FAULKES TELESCOPE AND T1MMCDONALD, TEXAS)Andre Deba kére, Double Star Commission, So iété Astronomique de Fran eE-mail: andre.deba kere�free.frAbstra tThis arti le ompletes a �rst publi ation on the dis overy of new ouples alled DBR 4 BC, DBR5, DBR 15, DBR 16 and DBR 17 with the roboti teles ope RIGEL of the University of Iowa.The new dis overies in this arti le are obtained witht the T 2m Faulkes Teles ope North, Hawaiiand the T 1m M Donald, Texas. These pairs are alled alled DBR 1 BC, DBR 13 BC, DBR 18to DBR 88. This brings to 78 the number of dis overies for 2015.Keywords : astronomy, double stars, dis overies, CCD, measurement.MethodThe method used for measurement is slightly di�erent from that used previously (using standard ouples to alibrate the images). To avoid errors due to �eld rotation we have hosen to take pairsof stars in the observed �eld.Choi e of 2 or 3 pairs of stars in the image �eld (10′ x 10′ ) whose angular distan e is less thanabout 20′′ .Use of the Astrometri a software and UCAC4 atalog to determine the pre ise equatorial oordinates (J2000 ) of these stars and to al ulate the polar oordinates of ea h pair. The Redu software then allows the average alibration of the images by determining the orientation of thesensor and sampling. Finally these parameters have been determined Redu software measurethe polar oordinates of double stars of the observed �eld.Table: Mean measures from observations in this paperWDS Name Epo h N θ ρ VA VB Catalog J2000.0 (pre ise)DBR (2015+)01071+3225 88AB 0.952 1 317.6 13.74 16.7 18.2 B1.0 1224-0019281 010708.27+322440.001071+3225 88AC 0.952 1 74.4 6.28 16.7 19.3 B1.0 1224-0019281 010708.27+322440.001071+3225 88AD 0.952 1 199.2 2.91 16.7 21.0 B1.0 1224-0019281 010708.27+322440.001073+3227 87 0.952 1 108.3 1.58 18.6 20.8 C4 613-003361 010717.30+322704.004048+2328 56 0.877 1 13.9 3.84 17.6 17.7 B1.0 1134-0054304 040446.14+232828.104078+6220 58PaPb 0.877 1 226.5 0.94 11.9 12.5 C4 762-029118* 040809.04+622007.104242+2412 57 0.877 1 255.5 4.80 16.6 16.9 C4 571-011176 042412.83+241145.706214+2646 18 0.927 3 28.6 4.55 13.9 16.4 C4 584-028158 062124.08+264620.206217+2645 15 0.927 3 309.0 2.21 13.8 15.2 C4 584-028228 062143.04+264454.006218+2649 19 0.927 3 314.4 4.17 12.5 15.3 C4 585-028193 062145.48+264837.906219+2643 20 0.927 3 129.8 3.68 14.3 17.9 C4 584-028267 062153.83+264234.006220+2646 21 0.927 3 22.6 2.85 14.1 17.9 C4 584-028292 062159.04+264538.106221+2645 22 0.927 2 109.4 4.27 14.4 16.4 C4 584-028320 062204.60+264458.206226+2647 16 0.534 3 303.1 3.03 13.0 15.4 C4 584-028468 062238.73+264642.106229+2629 24 0.927 2 226.2 3.29 15.2 19.3 C4 583-028399 062256.46+262929.319

FIVE NEW COMMON PROPER MOTION DOUBLE STARSAbdul Ahad, Luton, Bedfordshire, United KingdomE-mail: ahad8307�gmail. omAbstra t:In this paper �ve new CPM double stars are highlighted in the onstellations of Taurus, Orion,Mono eros and Canis Minor, urrently not listed in the WDS atalogue. On detailed binarityassessments, the omponents within ea h pair are shown to be within angular and physi al distan ethresholds in order for them to be gravitationally bound. Consistent alignment of proper motionsin various atalogues, oupled with lose angular separations, suggest these pairs are true binarysystems.

Figure 1: Sky panorama obtained by the author using his Canon300D DSLR at 03:30 UT on O tober 8, 2015.Introdu tionContinuing the sear h method and sele tion riteria des ribed in earlier papers, I had initiallyidenti�ed three new pairs. I ommuni ated them to Bob Argyle on the �nal day of September in2015. A further two pairs ame to light as in idental dis overies whilst examining entries fromthe WDS atalogue in the region between Pro yon and Betelgeuse near the Rosette Nebula inMono eros. I had the o asion to use a Canon 300D DSLR amera to obtain a 5-se exposurevista of the sky in whi h I indi ate positions of the new pairs as shown in Figure 1. The primariesbear Ty ho designations of TYC 662-1070-1, TYC 731-3258-1, TYC 170-9-1, TYC 177-1214-1 andTYC 192-627-1.Observations and AnalysisI observed on various nights using my 4.75-in h f/8.33 refra tor that sits atop a German equatorialmount. With a long fo al length of 1000 mm, I utilized a 6.3mm Super Plössl eyepie e to a hievea magni� ation of x159, whi h is the optimum power I �nd pra ti al for double star work. Clearautumn nights proved few and far between during O tober 2015, though the ones that were loudless were also remarkably both moonless and highly transparent at the same time, under22

whi h I made �eld drawings at the eyepie e as shown in Figures 2 through 6 below. The pair inTaurus, 03587+1055 (Figure 2) it must be stated was in fa t a visual dis overy I had made goingba k to the autumn of 2014, when I �rst re ognized it as a CPM binary not far from λ Tauri. Eventhough I had preliminarily sket hed this pair at that time, I did not pursue further an attempt topublish a paper on it until now.

Figure 7: 2MASS image of 06155+0842, showing dupli ity of theprimaryThe �rst thing to note is that the lose alignment of proper motions within ea h pair shown inTable 2, although relatively small in some ases, are all repeated a ross a number of independently ompiled atalogues. This repetition importantly assures the onsisten y of the data and makesthe primary ase that these are all bona-�de `CPM' double stars.Method of Calibrating Distan es and Spe tral TypesUnlike pairs evaluated in previous papers, olour indi es annot be straightforwardly mat hed tohorizontal positions on the H-R diagram to obtain spe tral lasses for a variety of reasons. Firstly,as we note in the ase of the se ond pair in Table 2 (06155+0842), some of these omponentsthemselves might be lose unresolved binaries. This would then imply that the B, V, J and Kmagnitudes have not been measured for a single sour e in every ase, whi h an make readingsappear redder on (B-V ) ompared to (J�K) and vi e versa, espe ially sin e both have not been24

measured instantaneously at the same epo h, with the possibility of unresolved omponents beingmisaligned.A ura ies of both (B-V ) and (J�K) olour index measurements, though, generally tend toget progressively worse with diminishing brightness. This is the prin ipal reason why the fainterB- omponents in some of these pairs appear bluer than their primaries. For a given amount ofexposure time, fainter stellar sour es provide lower photon ounts in CCD dete tors whi h anprove inadequate for a urate determination of spe tral types through onventional spe tros opi means. The B omponent in the �rst pair, 03587+1055, for instan e is of an obs ure V magnitudeof 12.03 and is stated to be of spe tral lass A3 `E' in SIMBAD. This is ertain to be in errorsin e its (B-V ) and (J-K) olour indi es both independently point to a horizontal position onthe H-R diagram of roughly F7 (Cox 2000, Ahad 2012)2,3. The SIMBAD ode `E' in fa t denotes�suspe ted� a ura y of data.Additional fa tors are interstellar absorption and reddening, whi h are fun tions of both distan eand gala ti latitude, leading to extin tions in visual brightness. With the ex eption of the �rstpair in Taurus (03587+1055), the remaining four pairs all lie along the plane of the Milky Way loseto the apparent path of the gala ti equator in the sky, where they would be visually obs uredby gas and dust in the interstellar medium. Light rea hing the observer from the Orion pair(06155+0842) in parti ular, having a gala ti latitude of just −3◦.9 and situated nearly 1,000light-years away in distan e, would be subje ted to some quantity of interstellar extin tion. Forstellar sour es lying along the plane of the Milky Way, extin tion is stated as 1.8 magnitudes per3,000 light-years (Whittet 2003)4. Although this �gure is a broad generalization, and in this asewhere the double stars lie in more tenuous regions of the Milky Way in dire tions looking almostdiametri ally opposite to that of the dense gala ti ore in Sagittarius, some extin tion in theirstated V magnitudes would still be signi� ant.In view of all of the onstraints set forth above and sin e no parallaxes have yet been determinedfor any of the stars in these systems, the most sensible method of inferring distan es was to befrom proper motions, where the greatest un ertainty is ±1.7 mas yr−1 in the ase of the pair inTaurus, 03587+1055 (Smart 2013)5.The `PM distan es' in Table 2 (stated in light-years) are therefore the urrent best estimates ofthe distan es from Earth. They were omputed through the me hanism of the negative exponentialpreviously determined by the author (Ahad 2015)6 and stated as:-y = 17941x−1.11By obtaining the partial inverse (domain y > 0) and putting the proper motions µ for y (inmas yr −1), the distan es from Earth, x, were found.The `likely spe tral types' shown in Table 2 are based upon analyti al judgments by reversing the omputational pro ess from the PM distan e. Absolute magnitudes were found from a ombinationof the apparent magnitudes and PM distan es using the distan e modulus, and these were then�tted to the (B-V )s to obtain spe tral lasses (Cox 2000)2. The spe tral lasses of primariesso determined are roughly onsistent with the more reliable (B-V ) olour indi es of the brighter omponents in ea h pair. The spe tral lasses of the ompanions are based on the ∆ ms and on thehigh probability that the two stars in ea h pair are lo ated at the same distan e given their loseangular separation in the sky and their ommon proper motion. All of these pairs are deemed tobe omposed of main-sequen e dwarfs (luminosity lass V) on the H-R diagram, whi h was foundto be the optimum statisti al �t between their apparent magnitudes and their PM distan es inthe distan e modulus. Taking the most distant pair, 03587+1055 as an extreme example, had its omponents been a pair of giant stars (of luminosity lass III on the H-R diagram) then, giventheir apparent magnitudes of 11.5 �12.0 their orresponding absolute magnitudes of around -0.5would have pla ed them at a vastly greater distan e of over 8,000 light-years away. This in turnwould have meant onsiderably smaller proper motions than the 8 mas yr−1 a tually observedwhi h, by the perspe tive e�e t, implies they are in fa t at the mu h nearer distan e of around25

1,000 light-years estimated in this paper.The measured angular separations (ρ′′ ) in Table 1 were proje ted out to the PM distan esstated in Table 2, and physi al linear separations, S, between omponents A and B were thenfound from the trigonometri al relation:-S = tan ρ × 63240 × PMdistance (there are 63240 AU in 1 light-year)Proje ted distan e separations between omponents A and B are shown in the �nal olumnin Table 2. The widest pair was found to be 07226+0620 where, at the stated PM distan e, thetwo stars would be physi ally separated by 5,800 AU. Both are F-type stars that are onsiderablymore massive than our Sun, and onsequently would be able to exert enough mutual gravitationalattra tion to hold together as a physi al system.All of the linear separations stated in Table 2 are in fa t within a eptable limits for orbital grav-itational intera tions to take pla e between the omponent stars, as was previously demonstratedby using the width of the α Librae system as a yardsti k7.Con lusionsThe �ve new pairs identi�ed in this paper have omponents that share ommon proper motionsrelative to the ba kground of �xed stars, as stated in independently ompiled atalogues. The omponents also appear to be positioned within su� iently lose angular and physi al distan ethresholds from ea h other for them to be gravitationally intera tive. On a balan e of probabilities,we therefore on lude that these systems are overwhelmingly more likely to be binary rather thanopti al in nature.A knowledgmentsThis resear h has made use of the Washington Double Star Catalogue maintained at the USNaval Observatory and the SIMBAD and VizieR databases maintained at the Centre de DonnéesAstronomiques, Strasbourg, Fran e.Referen es1.

The target stars were sele ted from theWashington Double Star Catalogue (WDSC) and were observed in Queensland from a latitude ofapproximately 27◦ S.MethodAn equatorially mounted 150-mm f/8 refra tor �tted with either a 2x or 5x Barlow lens was usedas required to obtain repeated images of the target pairs with a Meade DSI amera. The imageswere analysed using the astrometri double star program Redu 1. Approximately ten sta kedimages of ea h target were taken per night for seven nights and the results averaged to obtainmeasures of separation and position angle with su� ient on�den e.Full details of the method are given in Napier-Munn and Jenkinson2. Some re ent work on theerrors inherent in the method is des ribed in Napier-Munn and Jenkinson3. As pro� ien y has27

grown in the use of this equipment with the 150 mm refra tor, lose doubles with onsiderablemagnitude di�eren e between the omponents have been su essfully measured.ResultsFor all of the systems the WDSC information is �rst reprodu ed, showing the epo h 2000 position,magnitudes, separation, PA, and the last re orded measurement. The new measurements are thengiven in tabular form, in luding the mean and standard deviation and 95% on�den e limits. Anyun ertainties between the images and the last re orded measurements are dis ussed. Finally a on lusion is given as to whether any movement of the omponent stars has o urred in PA orseparation, based on the P-value for the t-test omparing the new mean values with the ataloguedvalue (P < 0.05 is onsidered as eviden e of hange).DUN247 Tu ana RA. 23 18.0 DEC. -61 00 Last Measure 2002 MAG. 6.9 & 8.2 PA. 293◦.0 SEP. 50′′.0

A pair that appear to be previously unlisted in theWDSC was found just to the west of B2450 and B2451. Using a 400-mm f/4.5 Newtonian re�e tor�tted with a Meade DSI 2 amera and software programme AstroPlanner V2.1 (Rodman) theobtained images were analysed using Losse's Redu software1. The mean 95% on�den e intervalsfor the B2450 and B 2451 measures were ± 0◦.290 in PA and ± 0′′.084 in separation. The resultswere as follows:System Last listed measure New measure CommentPA(◦ ) Sep.(′′ ) Epo h PA(◦ ) Sep.(′′ ) Epo h∗B2450 315.0 8.0 1930 347.38 14.03 2015.586 Clear movementB2451 225.0 7.0 1930 244.48 9.30 2015.586 Clear movementUnknown pair - - - 73.96 3.52 2015.633 No listing in WDSC?∗ Epo hs of new measures given in Besselian years as the average of the observations making up the measure.Introdu tionThese latest results are a ontinuation of the Astronomi al Asso iation of Queensland's programof measuring negle ted southern multiple stars. Observed from an approximate latitude of 27◦ S,target stars were sele ted from the WDSC that met the riteria of a minimum of �fteen years sin ethe last measure, and preferably with very few previous observations.MethodAll images were obtained using a Meade DSI 2 CCD amera oupled to an equatorially-mounted400-mm f/4.5 Newtonian re�e tor. Separations and position angles were measured using thesoftware program Redu (Losse), whi h is spe i� ally designed to measure double stars, usingappropriate images of the target pairs together with images of alibration pairs of known separationand PA; Argyle's4 list of alibration pairs was used for this purpose (Argyle, 2012). For thisopti al/ amera (Sony ICX429 752 × 582 pixel sensor) ombination FOV of approximately 0◦.2was al ulated using Argyle's list. The use of Redu requires input of the image s ale of theparti ular amera/s ope ombination. By using the same information from the alibration pairs,the image s ale mean an be al ulated over a number of nights. In this ase ten images onsistingthemselves of ten sta ked images per night over seven nights provided the ne essary informationto al ulate the mean. Using this opti al assembly to image alibration pairs beta Tu anae, thetaSerpentis and omi ron Capri orni, raw image s ales varied from 0.940 to 0.978, with a mean �gure34

of 0′′.96260 per pixel. This �gure is then used in Redu for all the target star redu tions. Theimaging and redu tion methods were des ribed in detail in DSSC 17.In order to obtain statisti ally viable results, the DSI software is used to sta k a minimum often individual good quality images as they are a quired, to generate one image for measuring.About ten su h images are obtained per pair per night, plus 3 trailed images with the tra kingswit hed o� in order to alibrate the E � W axis in the images. The Redu software is then usedto generate a single average measure for the ten images. This pro ess is repeated on 6 � 7 separatenights, generating mean separations and position angles together with standard deviations fromwhi h a on�den e interval for the measurement an be al ulated and a de ision made as towhether there has been a statisti ally signi� ant hange in PA or separation.ResultsThe results are presented below - being lo ated lose to ea h other both B2450 and B2451 wereimaged in the one �eld of view. The unknown pair, whi h appear to be unlisted in the WDSCwere found just to the west outside the FOV for B2450 & B2451.For the two known systems, the urrent WDSC information is �rst reprodu ed, in luding theepo h 2000 position, magnitudes (if known), PA, separation and year of last measure. One onlymeasure of ea h was made in 1930. The new measures are then given in tabular form, in ludingthe date of measurement, mean, standard deviation, and 95% on�den e limits (from the formulatαs/√n, where tα is the value of t for a 2-sided probability level α (in this ase α = 0.05), s is thesample standard deviation and n is the number of observations). An example of a relevant imageused in the measures is in luded. A on lusion is then given as to whether the pair has moved ornot. This is based on judi ious interpretation of three riteria in terms of both PA and separation:

The 2014 results were obtained with anequatorially mounted 150-mm f/8 refra tor �tted with a Meade DSI CCD amera.

In both ases software programme AstroPlanner V2.1 (Rodman)and image analysis software Redu (Losse) were used. The mean 95% on�den e intervals for thetwo measures are ±1◦.263 in PA and ±0′′.270 in separation.

Observed from an approximate latitudeof 27◦ S, this target system was sele ted from the WDSC meeting the riteria of a minimum of�fteen years sin e the last measure and preferably with very few previous observations.First imaged in 2014 with the 150-mm refra tor and 5x Barlow, the original redu tions al- ulated did not appear to mesh with the WDSC listed measures for RST5413A-B. A se ondprogramme of imaging arried out with the 400 mm re�e tor mid-2015 revealed the third ompo-nent and lari� ation by Argyle of the numbering methodology identi�ed it as listed in the WDSCas HJ4857A-C.MethodFull details of the method used to obtain statisti ally viable results an be found in Jenkinson2015. These details apply to both the use of the 150 mm refra tor and the 400 mm re�e tor, withthe same amera used on both o asions. 37

ResultsThe two results, along with a sample image are presented below. For both listings, the urrentWDSC information is �rst reprodu ed, in luding the epo h 2000 position, magnitudes (if known),PA, separation and year of last measure. The new measures are then given in tabular form,in luding the date of measurement, mean, standard deviation, and 95% on�den e limits (fromthe formula tαs/sqrt(n), where tα is the value of t for a 2-sided probability level α (in this ase α= 0.05), s is the sample standard deviation and n is the number of observations. An example ofa relevant image used in the measures is in luded. A on lusion is then given as to whether thepair has moved or not. This is based on judi ious interpretation of three riteria in terms of bothPA and separation:1. t-tests for a single sample mean omparing the new mean PA and separation values withthe single values given in the WDSC; P ≤ 0.05 was taken as eviden e of movement (that is, thenew mean is signi� antly di�erent to the single value reported in the WDSC, with 95% or more on�den e).2. Whether the last measure as re orded in the WDSC lies within the 95% on�den e intervalof our new measure (suggesting no movement) or not (suggesting movement).3. The absolute size of the hange; a statisti ally signi� ant hange that is very small is stillvery small and may not be of pra ti al signi� an e.Note that in a separate paper Napier-Munn & Jenkinson 20143, we have shown that the un- ertainty in PA in reases with de rease in separation, and the un ertainty in separation in reaseswith in rease in separation, for reasons dis ussed in that paper. `Un ertainty' here is de�ned asthe standard deviation of repeated measures.

A NEW VISUAL DOUBLE STAR IN AQUILAIan CosterE-mail: ian oster�gmail. omIntrodu tionWhilst observing the pair STF 2636 in Aquila using my 200-mm f/6 teles ope on 2015 Sept 27,at about 9pm BST (2000 UT) I ame a ross a pair of 9th magnitude stars about 1 degree ESEof that pair and whi h formed a neat triangular asterism. In my Baader zoom eyepie e at 24 mmfo al length (x50) the pair appeared fairly wide and the stars similarly bright. I assumed that theywould be already known to the WDS but when I he ked I found that they were not listed.I did �nd, however, that the primary of this `new' pair was the lose double star HDS 2883,whi h has omponents of 9. and 12. and is urrently seperated by 1′′.3. The Aladin/Vizierdatabase has a Ty ho number for the primary of the wide pair but not for the se ondary despiteits relative brightness. I ould �nd no entry for the se ondary in the stellar lassi� ation surveys.HDS 2883 was found by the Hippar os satellite and the WDS notes only two observations both ofwhi h were made in 1991 and whi h show no sign of any motion.

Figure 1: DSS image of un atalogued pair just left of entre (SERC J plate)MeasurementsI used the DSS olour image from the Aladin database (Fig. 1) to make the following mea-surements: separation: 20′′.7, position angle 113 degrees. This was done using a J band SERCS hmidt plate taken on 1982 Aug 18 with a resolution of 1′′.6 per pixel. The 2MASS images (inJ , H and K bands, Fig. 2) were taken on 1998 Sept 15 and ea h pixel represents 0′′.9 on the sky.I mentioned the new pair to Bob Argyle who subsequently was able to measure it with the8-in h refra tor at the Institute of Astronomy, Cambridge. On 2015.769 (2015 O tober 8) Bobfound a position angle of 112◦.4 and a separation of 19′′.51, but reported that the stars were loseto the limit of measurement due to the bright-�eld eyepie e illumination.Proper motionsLooking at the UCAC4 atalogue gave the following details:40

This raises an interesting question as to why the redder star isbrighter. It would normally be 0.5 magnitudes fainter than a G0 star at the same distan e. Onepossible explanation is that the primary has been lassi�ed as a Cepheid variable and is known asV1477 Aql. However, the GCVS have marked the star with the ode ' st' ( onstant).Con lusionsIt is quite possible that this is a ommon proper motion pair. The mean error is greater than thedi�eren e in proper motion. The similarity in spe tral type and the apparent brightness implythat the stars are at a similar distan e. Observations of parallax and radial velo ity would help toanswer the question about physi al onne tion.A knowledgementsThe author would like to thank the Centre de Données Astronomiques in Strasbourg for the useof Simbad and Aladin, and Brian Ski� and Bob Argyle for their assistan e in this investigation.Referen es1.

COMMONPROPERMOTION PAIRS ANDOTHERDOUBLES FOUNDIN SPECTRAL SURVEYS - 10. SURVEY WORK FOR 2015Brian A. Ski�, Lowell Observatory, 1400 West Mars Hill Road, Flagsta�, AZ 86001-4499, USAe-mail: bas�lowell.eduIntrodu tionThis report presents work on both known and newly-identi�ed doubles pi ked up while preparingvarious spe tral surveys in ma hine-readable form. It olle ts work done through most of 2015 inall parts of the sky. Follow-up measures are given from astrometri atalogues of pairs reportedby several observers, who often gave only a single observation (in luding myself!).URAT1The appearan e of the URAT1 star atalogue has made it possible to get di�erential measures at are ent epo h of many stars that were not resolved in earlier atalogues. The data were taken at theUSNO Flagsta� Station during a period of unusually loud-free weather from mid-2012 to early2014, perhaps ontributing to its su ess. The same 20- m f/10 `red lens' astrograph was used aswith the UCAC series, but with a new large-area CCD mosai amera (Za harias et al. 2015). Thelarge number of overlapping exposures has meant that the data are of high a ura y. The dynami range was also greatly extended by the use of an obje tive grating for some series of exposures �allowing measurement of bright naked-eye stars down to those as faint as mag 18 in the far-redinstrumental passband (around visual magnitude 20). Pretty good for a 20- m refra tor! TheURAT proje t was originally designed around a spe ial 1-metre aperture atadioptri teles opethat was not funded. Some wag thus joked that be ause of having to make do with the existingvery mu h smaller instrument, the atalogue should be alled �U-mouse" instead!The proper motions in URAT1 were determined from a mat h stri tly against 2MASS, another atalogue of high astrometri a ura y, but thus ignoring the long astrometri histories for millionsof brighter stars. The resulting motions seem to be mostly a urate, but are not pre ise, withun ertainty of roughly 5 to 7 milliar se /year be ause of the short temporal baseline. Thus anylikely ommon-motion pairmust be on�rmed by di�erential measures with a longer baseline, alongwith a onsideration of star olors and delta-magnitudes.Martin Ni holson has produ ed a large �le of some 9500 ommon-motion pairs identi�ed inURAT1. This an be queried star-by-star or obtained in toto from VizieR starting at:http:// dsar .u-strasbg.fr/viz-bin/Cat?I/330No mat h-up of the URAT1 pairs against the WDS was made, so a substantial fra tion of thepairs are already known, and no linkage of additional ompanions to known pairs was done. Inaddition, I have found quite a lot of URAT pairs that seem to have been missed; I am not surewhy they were omitted, sin e they fall within the range of Ni holson's sear h parameters. Su� eit to say that very many more systems remain to be identi�ed from URAT1, and this is giving usa mere hint of what's to ome from GAIA.Ralf-Dieter S holz (arXiv:1601.01896) has made a similar sear h for wide ompanions to nearby(i.e. bright) F-type stars using URAT1, but also making use of the WDS, the Ni holson list, andmany other resour es. This paper is well worth reading sin e S holz has done a thorough job, andbe ause it outlines his sophisti ated working methods ompletely.The WDS group at USNO-DC awaits all-sky ompletion of URAT before making their ownassessment of ommon-motion systems. The southern-hemisphere observations are underway fromChile. Thus URAT1 pairs will not be added to the WDS until some later date from an independenttrawl of the whole database. I have nevertheless reported several su h systems with additional43

Pairs identi�ed after Ni holson's list be ame available at VizieR in 2015 May, spe if-i ally by my alling them out as su h to the WDS folks, are being assigned the dis overer a ronym`UR' � there are seven su h systems in the list below, and all are highlighted in the notes.In the table below I also give a signi� ant number of measures for known pairs from URAT1,readily identi�able by having a single entry with URAT1 as the sour e. These serve as he ks invarious ways on the usefulness of the atalogue and also to extend the baseline of measures.Other survey workAmong other surveys, I have ompleted work on the Orion region emission-line stars. This yieldedabout 40 additional pairs beyond the 140 systems des ribed in paper 8 (Ski� 2015). To me this isquite a surprising density of doubles in su h a small area of sky. I have begun to have a look atother star-forming regions, mainly through George Herbig's work on late-type emission-line stars.These regions are, however, generally rather more distant than Orion, so resolved pairs are far less ommon.Another obje tive-prism survey omprises about 5000 stars in the region of the north Gala ti pole lassi�ed by Art Upgren (1962, 1963). While obtaining a urate positions of these stars forthe �rst time, I identi�ed several dozen new ommon-motion pairs. The work was ompleted afterthe table below was losed, so not all of the pairs have been submitted for the WDS, and thus44

omitted here. The omplete revised Upgren atalogues are available from VizieR as items III/9Band III/10B.I also went over a onsiderable number of stars in the region of the Pleiades, working from earlyhistori al star-lists. This yielded a number of ni e pairs, though most are non-members. Workingover a list of nearly 6000 stars by Wallenquist (1939), who observed the Ophiu hus dark louds andthe large Sagittarius star loud from Java, I found several blue pairs superposed near the Gala ti entre. Several known pairs in this region are shown below that were found by Rossiter but not on�rmed sin e his �rst observations until now.Pairs north of about +60◦ De were identi�ed while going over spe tral types determined for theAGK3 star atalogue and published by Albert Balz at M Cormi k Observatory. The M Cormi k atalogues in lude some 60,000 stars between mag 9 and 11, so there is more to ome from thissour e. Similarly, pairs in the northern winter Milky Way are oming mostly while obtainingpre ise oordinates for HDE stars in the region.As before, large tables, some 210 spa es wide, were prepared for submission to the WDS folks.This allows the WDS database to be populated dire tly with omplete `best' information gleanedfrom VizieR and SIMBAD. Here I show a mu h simpli�ed table, stripped down to only the measuresand astrometri sour es. A large number of omments are added below, indi ated by an asteriskfollowing the WDS designation. In the olumn of data sour es, I adopt a ronyms for ommon atalogues, but also show standard 19-digit `bib odes' for papers in the literature that ontainastrometry. Only o asionally did the authors of these papers re ognize the doubles involved orintend the data to be used in this way. Interestingly, when a spe i� paper is the �rst item in theastrometry list for new pairs, the WDS folks are assigning the dis overer a ronym to them (e.g.WDS 03287+3118 below), so the authors are unsuspe tingly getting double-star designations theydon't know about.Referen esSki�, B.A., 2015, Webb So iety Double Star Se tion Cir ulars, 23, 40Upgren, A.R., 1962, Astron.

primary is an estimate from photometri olors; it is not as late as K8V per Vyssotsky.From CCD photometry 2015 Jul - 2016 Jan, I �nd the primary to be variable presumablyfrom spottedness with a period of 9.3 days. Figure 1 shows the phased V-band light urve.03249+6709 The ompanion is possibly a ool white dwarf: it shows intermediate-red olor on images,and 2MASS J − K = 0.27, though the photometry is un ertain.03287+3118 In the region of the nebulous luster NGC 1333.03289+3118 In the region of the nebulous luster NGC 1333.03290+3120 In the region of the nebulous luster NGC 1333.03461+2500 These are Pleiades non-members. omponent B is visible only on UKIDSS images; itsmagnitude is a guess. The measures of AC are somewhat jittery possibly due to thevarying in�uen e of omponent B between visible and near-IR.03465+2405 Probably not Pleiades members.03482+2315 The Luyten 1960 measure is an estimate only; these are Pleiades non-members.03498+2345 This pair, nearly 50' apart in the �eld the Pleiades, have remained �xed sin e 1894.03515+2350 This pair appears in original 1923 Hertzsprung Pleiades atalogue (they are lusternon-members), yet overlooked sin e then. Hertzsprung's atalogue measures are given to1′′ only, so are no good in themselves; alas, there is little other astrometry.03530+4557 All three stars are blue.03596+2118 The ompanion is not as red as expe ted; UKIDSS J − K = 0.68, but rowding maybe a problem (there is a lose opti al ompanion on its E side at the UKIDSS epo h).The star is a ool white dwarf if the olor is orre t. The pair are evidently in theba kground of the Hyades with radial velo ity distin tly di�erent from the luster.The implied moderately-high spa e velo ity suggests thi k-dis kinemati s �the UVW omponents are approximately +20, -80, +70 km/se .04037+1927 The faint star is a new Hyades member; ommon motion is lear from 2MASS/UKIDSSK-image blink. All the measures are un ertain due to bright primary and proximityof the ompanion.04093-2025 This is a new distant M-dwarf ompanion to a well-studied lose binary.04100+5559 This moderate-motion K-dwarf has a lose ompanion that is just visible in 2MASS images,from whi h an un ertain estimate is given. The primary is a short-period e lipsingbinary, whi h I have on�rmed via new CCD photometry.04119+2338 This is the fourth omponent of a well-studied Hyades spe kle/spe tros opi triple; ommon motion is lear from 2MASS/UKIDSS K image blink. The measures are un ertaindue to the bright primary and proximity; the magnitude of the ompanion is likewisevery un ertain.04272+4359 This is the �rst on�rmation.04281+1352 This is a new Hyades binary.04324+2422 The primary is NSV 16067 (suspe ted variable with 0.8 mag amplitude), but my CCDphotometry in winter 2014/15 shows it onstant at only about 0.01 mag rms.04342+1133 Another new Hyades binary; the primary is a known lose spe tros opi binary.82

04351-1204 Con�rmed opti al.04410-2223 Only �maybe" ommon-proper-motion, but the spe tral-type, olors, and magnitudes are onsistent with a K-giant + F-dwarf pair.04551+3535 The WDS had an ID error, now orre ted. the pair was sought but missed by Wul� Heintz;I re overed it only 1′away, though the stars are mu h fainter than originally reported.04585+4758 The stars are in a nebulous knot in the �eld of the HII region Sh 2-217.05172+3922 The stars were reported by Varri att et al., 2010MNRAS.404..661V. The ompanionis greatly obs ured, and hardly visible even in the 2MASS J-band image. These area very distant massive pair of young stars in an obs ured star-forming region exhibitingspe ta ular ollimated out�ows. Three other less interesting pairs/trios in this luster have been reported by Nikoghosyan & Azatyan in arXiv:1501.06717 using theVarri att UKIRT images.05226-1953 The revised Hippar os parallaxes are small but nearly identi al: 2.9 and 2.7 milliar se onds.05229-1501 The ompanion is a newly-identi�ed white dwarf.05233+3445 Con�rmed opti al due to the motion of se ondary: it is a foreground G dwarf.05275-6922 In the foreground of the LMC.05283-6938 An M-dwarf pair in the foreground of the LMC.05283-1931 The physi al link is un ertain; the primary is an e lipsing binary.05311+0945 The ompanion is visible in the WISE 3.4µ image, but is not in the atalogue.The new estimate is nevertheless a ni e ar -extender on�rming the ommon motion of thisM-dwarf/white-dwarf pair.05332-2154 The physi al link is on�rmed via RAVE radial velo ities: +35.8 and +36.3 km/se .05349-0528 This pair previously had an entry but no a tual measurements in the WDS.05355-0506 The primary is about V mag 20. this is a greatly obs ured Orion protostar within amole ular out�ow.05411-2434 First noti ed by Annie Cannon in the original HD atalogue.05492+0436 Common motion is lear from POSS-I/II blink; the imaage estimates are very roughbut on�rm the �xed orientation despite 7′′sky-motion over the 55-year baseline.05515+1217 Must be opti al due to spe tral type mismat h: an A0 dwarf and ba kground late-K giant.05529+1609 Two blue stars; a third star 7′′ NE is a ba kground K/M giant.05535+3217 The WDS 1899 measure probably has a quadrant �ip, so that pa 197 is intended, not pa163.05537+3007 Two K-type giants; the UCAC2 proper motion for primary is wrong due to a bad linkage.05573+1708 A ommon-motion pair already known from the LSPM; lose to the 25 p �nearby" radius.both stars show IPHAS photometri H-alpha ex ess, so are likely to be relatively young.05588+2351 The WDS previously had an ID error; the pair is not HD 249772 = BD+23 1134.06009+2356 First on�rmation sin e 1971. 83

06023+1633 The ompanion seems too red to be an M-dwarf, and is possibly an opti al ba kgroundM-giant.06030+1804 The 2MASS olors suggest late-B and early-A pair.06136-1527 Essentially �xed from a POSS-I/II blink, and also from the measures here. The AC2000measure of the primary has large un ertainty. thus I think the WDS 1906 measure has thewrong position angle (or perhaps pa 254 intended, not 214?).06205+8501 Components AB are on�rmed as opti al. The new omponent C was identi�ed byNi holson in URAT1. This unusually faint red ompanion was missed in the LSPM (itappears only on the POSS-I red plates), but is on�rmed as having ommon motion bythe di�erential measures here.06260-1657 Previously this had a WDS oordinates error (the LDS position was orre t), and the 19992MASS measure was for the wrong pair.06297-1212 The slow monotoni trends in both pa/sep suggest this is an opti al pair. Also thereis a olor mis-mat h � both are K-type dwarfs despite the large delta-magnitude.06394+0938 A low-mass T Tauri binary in the �eld of NGC 2264.06407+0952 A low-mass T Tauri binary in the �eld of NGC 2264.06408+0954 A low-mass T Tauri binary in the �eld of NGC 2264.06488+0023 Additional measures and two new ompanions are shown for this system,whi h is the entralstar in the trapezium of the open luster Bo hum 2.06526-1811 Component B is not real due to an Astrographi Catalogue error. The physi al link ofthe new omponent is un ertain, but it is present on 2MASS and SDSS images.A red M-giant 19′′ south is a ba kground star.06537-2423 How did su h a bright large-motion pair get overlooked previously?06549-1231 Re ognized as double by Annie Cannon in the original HD atalogue.06574-1821 First on�rmation sin e 1932.06584-1300 A new third ommon-motion omponent to a known 'nearby' (22p ) K-dwarf binary.06595-0405 The primary is an outbursting FU Ori-type obje t; the ompanion was noti ed in follow-upspe tros opy by Reipurth.07025-0342 All three omponents here were measured by Nesterov et al. for their HDE atalogue revision. The loser Barton omponent is rather red (2MASS J − K = 0.94)and is most likely a ba kground K giant. the new southwestern omponent is onlyslightly less blue than the primary and is possibly a physi al ompanion.07027-1341 First measure sin e 1954.07257-2351 The fainter star of this opti al pair has large proper motion. S holz et al.(arXiv:1501.00929) give many details about the high-velo ity star.07474+2438 These stars have been re ently identi�ed as two ool white dwarfs by Gianninaset al. in arXiv:1503.0306509200+6412 This pair lies in the �eld of the NGC 2805 galaxy group, and was pi ked up visuallyby Chris Luginbuhl and myself during preparation of our �Observing Handbook and84

Catalogue of Deep-Sky Obje ts". I was surprised to �nd they are a good ommon-motionpair.09251+2915 Courtot pair from Webb So iety DSSC 23; opti al.09251+2933 Courtot quartet from Webb So iety DSSC 23. all the omponents relative to A are opti al,but stars C and D are possibly related as indi ated by the new measures.BDS 5413 Another of the many star + galaxy (or nebula) pairs in the Burnham �General Catalogue".The Burnham and Barnard measures are not pre essed. The trend in the measures is dueto the motion of the star nearly due south.11083+1513 The primary is a tight double-degenerate with a spe tros opi radial-velo ity orbit of only0.12 days period (Gianninas et al., arXiv:1509.07134). these authors overlookedthe nearby M-dwarf ommon-motion ompanion.11230+6443 This is a new faint omponent to known AG pair with a long astrometri history.11378+4150 Component C is learly opti al from a POSS-I/II blink.11478+3514 The primary is the W UMa-type e lipsing binary KM UMa.11479+4855 The ompanion is signi� antly bluer/hotter, and thus opti al unless the primary is asubgiant (whi h is not unreasonable).11498+4637 Looks like a ni e hierar hi al triple.11499+3754 Component C already identi�ed by Ni holson from URAT1, but he missed link with theCouteau pair.12033+2902 Component B is not present on SDSS or 2MASS images: it either does not exist orapplies to some other star.12041+3707 This is the �rst on�rmation.12049+3842 Con�rmed opti al; the 1830 Hers hel measure is learly only an estimate.12048+3958 Luyten gave the position angle to the wrong ompanion, whi h has motion orthogonalto primary. The orre t ompanion has similar motion but is learly opti al, obviouseven from blinking POSS-I/II.12110+3857 The measures are unusually onsistent.12114+4334 The Luyten 1960 separation for AB is wrong.12344+4517 Slight relative motion? Possibly opti al.12381+4155 The brighter star 15′′ NW is unrelated.12388-5113 All the ompanions are opti al, and all were �rst measured spe i� ally by Rousseau.12411+4316 Already identi�ed by Ni holson from URAT1.12463+3341 Component B omes up very strong toward the near-IR, and seems likely to be physi al.Component C is more likely to be opti al � but the physi al link is un ertainin both ases.12543+4108 Opti al, but the motions are very similar.12560-1257 The ompanion was �rst reported by Gauza et al., arXiv:1505.00806. The primary85

is V mag 17.8; the se ondary has Sloan i = 22.5, so about V mag 26. Gauza et al. assignun ertainties of 0◦.2 and 0′′.03 to their measure from VISTA teles ope images.12582+4153 Con�rmed opti al, also obvious from POSS-I/II blink.12584+4156 Additional measures of the loser Damm ompanion are given, but also a new more distant omponent added. The measures of the latter are a bit equivo al, so this ould be anopti al ompanion.13103+6410 The third omponent to lose Muller pair is very faint, but seems okay.13110+6631 Looks �xed 1957-2013, but earlier measures are s attered.13379+0643 Already identi�ed by Ni holson from URAT1.14106+0528 A fourth omponent to known trio.14199-4103 The added baseline now shows this pair is learly opti al.15093+6640 A ni e hierar hi al triple in luding a mat hed pair of M dwarfs. The mag 11 star 32′′east of omponent A is unrelated.15118+6151 Component C is obviously opti al.15145+6454 Con�rmed opti al.15358+1044 Obviously opti al from POSS-I/II blink, mostly due to motion of primary.15404-7327 The primary is κ2 Apodis.16203-7842 This system involves the bright orange stars δ1,2 Apodis and a third ompanion. The early La aille measurement is better than expe ted, and extends thetemporal baseline past 250 years.16519-3803 µ1,2 S orpii. these measurements merely demonstrate the long-known link betweenthese two bright star systems. The pair of ourse were known in pre-teles opi times,but la ked a WDS entry. The early measurement by La aille is relatively poor (thoughwithin his usual errors), but shown for ompleteness.17115+6646 This white-dwarf/M-dwarf pair were previously reported at least as early as Green et al.,2000ApJ...540..992G17391-2656 First measured by Rousseau.17446-2631 A very red ba kground star lies 7′′ NW.17495-2729 This is the �rst measure sin e 1940.17512-2358 The loser omponent B will likely turn out to be opti al, and just a ba kground M giant;its magnitude is a guess. Component C was found from blinking POSS-I/II.17548-2839 A likely opti al pair, but lose and similarly bright.17592-2842 First measured by Nesterov et al.; likely opti al, but lose and similarly bright.17596-2903 Probably opti al, but worth noting due to the mixed nomen lature in the literature.The brighter star visually is a late-type probable K-giant, but the HD type is A2(Wallenquist gives A0), whi h learly refers to the blue ompanion, slightly brighterin the blue. The Cordoba, Yale, and Ty ho-2 atalogue entries all refer to the red star,but the CPD entry is probably for the two stars ombined.86

18005-2341 Components C,D,E were added to disambiguate a rowded little group; their magnitudesare very rough. Stars C and D are ba kground ool giants that are prominent in the near-IR.18027-2306 This is the �rst measure sin e 1943.18055-2326 This system ould be mistaken as a "hot star with IR ex ess": instead the early-B primaryhas two red stars within 2′′ radius.18106-2744 This is the �rst measure sin e 1944.19040-0419 Component A is an un ertain spe tros opi binary; omponent B is likely to be an unrelatedM-giant. Components CD are a loser pair near the Wolf-Rayet primary; their magnitudesare un ertain.19355+1148 Con�rmed opti al.19518+2614 Argyle pair from Webb DSSC 23; opti al due to spe tral type mismat h.20156+0615 De�nitely opti al; they are a K dwarf and ba kground G dwarf, so also amagnitude/spe tral-type mismat h. Some of these measures are probably already in WDSdatabase.20315+4113 The primary is Cyg OB2 3, and is an SB2 e lipsing binary. Details are provided by Kiminkiet al. in arXiv.org:1508.03108, who treat this as a new pair, but provide useful spe traland photometri data for this system of O-type stars.20442+0648 Another good hierar hi al triple.20478+0007 Given as DA + M from SDSS spe tra (e.g. Eisenstein et al. 2006ApJS..167...40E et seq.).The M star has a distin tly di�erent lo ation on longer-wavelength images than thewhite dwarf � both stars are visible in Sloan i-band image, so an estimate is shownfrom that, along with the Sloan/UKIDSS kludge.22299+5225 The URAT1 measures help put this opti al trio on a better footing.22399+0019 Reported by Kili et al., 2010ApJS..190...77K. omponent A is a DC white dwarf,while B is an 'ultra ool' white dwarf, mu h redder than omponent A.22541+5737 Already identi�ed by Ni holson from URAT1.23313+4613 It seems odd that Popovi did not see the third star here.23381+4502 The bright (mag 10) ompanion 23′′ southeast is opti al; a mag 16.5 star 5′′ N ould be physi al (not measured here).
