GCN Circular 12097
P.H.T. Tam and A.K.H. Kong (NTHU) report: We report on the detection of >100 MeV gamma-ray emission from the direction of GRB 110625A (Swift trigger 456073; Page et al., GCN #12088) using the Fermi Large Area Telescope (LAT). The GRB position was outside the LAT field of view (i.e., >75 deg with respect to the LAT boresight) at the burst onset (T0; 2011-06-25 UT 21:08:28; GCN #12088). However, prominent emission up to several GeV was detected from the GRB direction around T0+200s to T0+500s, during which the light curve seems to resemble a double-peak structure. Using the data obtained from the above period, we localized the LAT emission at RA, DEC (J2000 deg) = 286.6, 6.9, with a statistical error of ~0.3 deg (68% CL), which is compatible with the refined Swift/XRT position (Page et al., GCN #12092). A preliminary spectral fit gives a photon spectral index of around -3 at energies above 100 MeV.
