One of the more surprising results of the Compton Gamma-Ray Observatory (CGRO) was the EGRET discovery of an 18 GeV photon associated with GRB 940217 1.25hr after the burst, much longer than the duration of the burst at lower energies. In the Fermi era, such extended high-energy photon emission (> GeV) has been discovered in many GRBs detected by the LAT, strongly suggesting that late high energy emission might be a generic feature of all such events. We are searching lower flux LAT events to test whether the previous observations of more prominent GRBs can be extrapolated to lower intensity bursts.
