NEWS NOTES

EX-PRESIDENT JAILED

It is with deep regret that we announce “the untimely departure of David Harrington

from the ranks of the Warren Astronomical Society. Dr. Harrington, accomplished amateur

astronomer and chemical engineer, began serving his 20 year sentence for defamation of

character in the Jackson State Prison last week.

Dave is best remembered for his fight to construct an amateur astronomical

observatory in the Detroit suburb of Troy. After a lengthy court battle, he was allowed to

complete his observatory even though he was found guilty of interfering with his neighbor's

television reception. Applying his professional talents to the project, the observatory was

outfitted with a lunar energy collector to provide energy for his clock drive. “After all,” said

Dave, “lunar energy is the coming thing and I do use the observatory primarily at night.”

Although functional, the collectors also serve as a moon dial and coffee maker.

During his career as an amateur, Dave acquired the nickname “Hard-luck

Harrington” for his eclipse expedition disasters. Although he spent a considerable amount of

time and money studying satellite cloud photos prior to each eclipse, he always managed to

find the cloudiest viewing sites. His luck changed after the 1972 eclipse when someone

pointed out that he was mistaken in his analysis of cloud patterns. It seems Dave studied

infrared photographs which indicated cloudy areas as dark instead of white as normally

shown. “They really fooled me on that one,” he commented later.

Dave's career as a chemical engineer spanned both the aerospace and automotive

industries. After 10 diligent years, he received his Ph.D. from the Michigan State University

Extension Service in Ann Arbor. Soon he began work for General Motors at the Technical

Center in Warren. His work in fluid dynamics led to many awards and recognitions.

Unfortunately, his career took a sudden turn for the worse the first year he was elected

president of the Warren Astronomical Society. After driving in a fellow club member's Toyota

Celica, he sold his newly acquired Delta 88 and purchased one for himself. The next day, he

stormed into a design meeting and demanded an explanation why General Motors couldn't

design a car that had as much quality and efficiency as the Celica. Soon after receiving his

pink slip, he quipped “I asked for it, and I got it!” When asked about his future, he replied

“Plumbing and air conditioner-repair are highly related fields. You can't complain about the

wages either.”

Ironically, it was the same court that granted his lifelong dream of owning his own

observatory that also put an end to his freedom. In the landmark case “The Defamed of the

Warren Astronomical Society vs. Dave Harrington”, 11 members of the club who had been

subjects of one of Dave's numerous satires successfully sued him for his observatory and had

him put away. The “Defamed 11” as they became known received much legal advice from

lawyers representing Faitus Enterprises, the now billion-dollar corporation once satirized by

Dave. At the end of the trial, Dave shouted “I was only joking!” So were they.

A BRIEF SURVEY OF THE MINOR PLANETS

By Ken Kelly

Minor planets are small bodies of the Solar System, the largest being 945 km in diameter and the smallest being less than one km in diameter. All but a few of them spend at least part of the time between the orbits of Mars and Jupiter. Orbits have been calculated for over 8100 of them, but only 3408 of them are known to high enough precision that they can always be located. These are the ones with permanent numbers. Six planets were given numbers but were never seen again, hence are lost.

Of the 8140 with calculated orbits, 7380 are located within three main belts, called Main Belts I, II and III. The separation between the belts is determined by resonances with the planet Jupiter. These separations are called Kirkwood gaps, after the person who discovered them.

Main Belt I has about 2840 objects and is divided into two parts. The inner part has 1340 objects with very similar orbits. These are called the Flora family, after the first one discovered. They appear to be products of fragmentation. At one time there were four objects which collided, broke UP and their products collided and broke up until there are now over 1300 fragments.

The outer part of Main Belt I contains the Nysa family with 140 members, also a product of collisions. Nysa, the prototype, is 72 km in diameter and has the highest albedo known for any rocky body, 48 percent.

Main Belt III has over 2400 objects, and contains three smaller families of collision fragments. These are called the Themis, Koronis and Eos Families. The largest is the Themis family with over 350 objects. The other two have over 160 objects in each.

Main Belt II has about 2100 planets. Its largest family of collision fragments is the Maria family, with about 50 members.

Each of the three belts contains one large object which dominates. Main Belt II has Ceres, 945 km in diameter, the first minor planet to be discovered. Main Belt I has Vesta, the only one bright enough to be seen with the naked- eye. In June of 1989 it will be as bright as magnitude 5.6. Vesta is 555 km in diameter.

Main Belt III has Hygiea, which is 525 km in diameter. The third largest minor planet is actually Pallas, with a diameter of 538 km. It is the largest of a small family of 13 objects which are at a high inclination of 35 degrees. It will be a prime target for a radio interferometer in a future century.

The fifth largest minor planet is Chiron, whose diameter is 400 km. It is also the farthest out, traveling between the orbits of Saturn and Uranus. It is one of only a very few objects which does not spend at least part of its time between the orbits of Mars and Jupiter. No other minor planet exceeds 340 km in diameter.

There is another family of planets within Main Belt I which is isolated by resonances; this is the Phocaea family with 80 members. Although they may have taken place, collisions do not appear to have been a major factor in its formation.

Page 6: WARREN ASTRONOMICAL SOCIETY · WARREN ASTRONOMICAL SOCIETY PAPER Editor: Ken Kelly / 839-7250 Send all articles to: THE WASP, P.O. Box 474, East Detroit, MI 48021 The W.A.S.P. is

Another group of planets which were isolated by resonances is the Hungaria family with a mean distance from the sun of about 1.95 A.U. (Astronomical Unit) which is just outside the orbit of Mars. This is subdivided into several small families of collision fragments. A few of the Hungarias penetrate the orbit of Mars, but not very deeply.

There are at least 250 planets which either completely cross the orbit of Mars or penetrate it deeply. The ones which do not approach the earth's orbit within 1.30 A.U. are called Mars crossers, and there are at least 160 of these.

Forty three planets have their perihelion distance (closest point to the sun) between the orbits of the earth and 1.30 A.U. These are called Amors, although Amor was not the first in this group to be discovered.

Forty five known planets cross the earth's orbit at the present time. All but six of these are called Apollos, after the first one discovered. The other six are called Atens, and they are distinguished by having their mean distance from the sun less than 1.0 A.U.; these should be classed with the inferior planets Mercury and Venus because the orbit is inferior, or smaller than the earth's. Another interesting fact about the Atens is that only one of them penetrates the orbit of Mars. One unnumbered Apollo also does not penetrate this orbit, but all other Apollos and Amors do cross or at least penetrate it.

There are other interesting minor planets outside of Main Belt III, including the Cybeles, the Hildas and the Trojans. The Hildas have a period of revolution about the sun of about eight years, which is two thirds that of Jupiter. There is a lone object with a period of nine years, called Thule. The Trojans are in two groups, both of which travel in the orbit of Jupiter. One group is traveling about 60 degrees ahead of Jupiter but the other group is 60 degrees behind; there are at least 50 objects in each group.

One mysterious aspect of minor planet behavior is that planets with periods greater than six years tend to cluster about resonance points with Jupiter while planets with periods of six years and under tend to avoid these regions, hence the Kirkwood gaps. No one has yet found a satisfactory explanation for this behavior.

THE MIAMI VALLEY ASTRONOMICAL SOCIETY AND

THE DAYTON MUSEUM OF NATURAL HISTORY

INVITE YOU TO ATTEND

APOLLO RENDEZVOUS AND TELESCOPE FAIR Hosting

GREAT LAKES REGIONAL CONVENTION OF THE ASTRONOMICAL LEAGUE

June 13th and 14th, 1986

Apollo Rendezvous and Telescope Fair, hosted by the Miami Valley Astronomical Society and the Dayton

Museum of Natural History, initiates the summer season of gatherings for the amateur and professional

astronomers of the Midwest. Held the second weekend in June of each year, Rendezvous offers the first

opportunity for exchange of information on astronomy, telescope making, and related subjects. This year, the

Great Lakes Region of the Astronomical League will be holding their annual meeting in conjunction with

Rendezvous.

On Friday evening, registration begins at 6 pm in the Apollo Observatory where attendees sign in and gather their

Rendezvous materials. At 7:00 pm, there wi1l be an informal slide presentation by Rendezvous participants.

Attendees are encouraged to bring slides and photographs of their projects and activities to share with fellow

astronomers during this relaxed program session. A star gaze at 9:00pm will be held on the Museum grounds; the

50 cm Cassegrain in Apollo Observatory and the telescopes in the Junior Observing and Training Center will be

available.

Saturday brings our major activities. The day begins at 8:00 am with registration, the setting up of private and

commercial displays, the Telescope Fair, and the Flea Market. The opening Paper Session kicks off at 9:00 and

at 11:00 adjourns for the Great Lakes Regional meeting. Allowing time for a lunch break, activities continue

throughout the day. The second paper session begins at 1:30 pm and concludes at 4:00 pm. At 4:30 pm, our

Principal Speaker will present a program. Following this presentation, at 5:30 pm, awards, door prizes, and

certificates of merit will be presented.

Our final event will be a star gaze, to be held at the John Bryan State Park Observatory, our dark sky location in

nearby Yellow Springs, Ohio. This will begin at 9:00 pm. Our 16” and 12” newtonians and 9" refractor will be in

use. Maps and directions will be provided.

Bring your telescopes! Join us for an enjoyable Friday evening of star hopping, show off your instruments on

Saturday, then join us again Saturday night at John-Bryan State Park.

CALL FOR PAPERS

If there is one activity that sets our meeting apart from a simple gathering of astronomers, it is the continuing

quality of presentations of ideas and activities by participants. This year, we will continue this tradition of sharing,

with colleagues, our thoughts and inspirations regarding astronomy, astronomical methods and instrumentation,

equipment and design.

You are invited to present a paper, on any subject of common interest during either of our paper sessions. Please

send an outline or Abstract to the Chairman, Apollo Rendezvous, P.O. BOX 20268, Dayton, OH 45420. A brief

biographical sketch would be appreciated.
