Flare recorded by the Solar Dynamics
Observatory (SDO) on the night between
14th and 15th February 2011.
It is a solar flare, of category X2, followed by an important Coronary Mass Emission (CME)
This kind of flares are constantly monitored since they can have relevant consequences on Earth
Valentine’s Day Solar Flare

Program for the future
Study efficiency of the detectors as a
function of temperature and
pressure
Determining a correction coefficient

In practice
During the data acquisition the efficiency of the
stations EEE varies
Vary the frequency of counts μ
The objective is to study how the efficiency varies by comparing it with a small telescope scintillators

ConclusionsThe EEE experiment in the area of Bari:
3 active telescopes EEE
The Altamura telescope acquire data almost continuosly from 3 years
First school to observe two Forbush decrease
In the near future, with 3 telescopes, we want …… to study detector performance under varying weather conditions… look for coincidences in the middle distance… continue the observation of cosmics phenomena
EEE produces physics and …
