Valentine’s Day Solar Flare 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
Counts of cosmic rays - Altamura telescope Decrease Forbush The Valentine’s Day solar flare as observed by the EEE Altamura telescope
Forbush March 2012 Preliminary! Second solar flare observed by the EEE Altamura telescope
Program for the future Study efficiency of the detectors as a function of temperature and pressure Determining a correction coefficient
It is a known effect on the RPC detector... Pressure Temperature
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
Conclusions • The 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 …
