The trigger method detected activity at E > 20GeV/(1+z) with TS ~44 and emission up to 54 GeV from 2015-09-03 to 2015-11-16, following the prescription of Pacciani et al. 2014, ApJ, 790, 45. The flux integrated on the whole period is (32.1+-1.6)E^-8 ph cm^-2 s^-1 (E > 0.1 GeV), and the gamma-ray photon index 2.20+-0.06.ELETTRONICOenMagazine articlehttp://www.astronomerstelegram.org/?read=8323
