Abstract

We report γ-ray afterglow observations of GRB 110625A using Fermi’sLarge Area Telescope (LAT) above 100 MeV. Gamma-ray emission was clearly detected usingdata taken between 180 s and 580 s after the burst. The GeV light curve differs from apower-law decay, and probably consists of two emission periods. Simultaneous Swift/XRTobservations did not show flaring behaviors, distinguishing its origin of the extended GeVemission from the case of GRB 100728A.
