The trigger method detected activity at E > 20GeV/(1+z) with TS ~79 from 2015-12-10 to 2015-12-30, following the prescription of Pacciani et al. 2014, ApJ, 790, 45. FERMI-LAT detected Two Gamma-ray photons of about 50 GeV within the last week.ELETTRONICOenMagazine articlehttp://www.astronomerstelegram.org/?read=8483
