Abstract

The EEE (Extreme Energy Event) Project is aimed to the study of Extensive Air Showers (EAS) and correlated phenomena. The experimental setup is composed by an array of more than 40 tracking telescopes, based on Multigap Resistive Plate Chambers (MRPCs) technology and distributed over a wide area covering more than 3 105 Km2. Among the different fields of investigations, the EEE telescope array is suitable for detecting galactic cosmic rays flux variations, referred therein as GCRD, mainly via the secondary muon components. Such variations are directly related to solar flares and coronal mass ejections occurring on the solar heliosphere. Four variations have already been observed in 2011, 2012, 2014 and 2015 showing the array has the capability of becoming a stable survey for GCRDs over a broad surface and more than 10 in latitude and longitude.
