GCN Circular 20229
G.Vianello (Stanford), F.Longo (University and INFN, Trieste) report on behalf of the Fermi-LAT team: On December, 02, 2016 Fermi-LAT detected high-energy emission from GRB 161202A, which was also detected by Swift (GCN 20227). The best LAT on-ground location is found to be RA, Dec = 356.95, 19.49 (J2000) with an error radius of 0.13 deg (90 % containment, statistical error only), which is fully compatible with the enhanced Swift/XRT position reported in GCN 20228. This was outside the field of view of the LAT at the time of the trigger t0 = 23:12:52.7. The location of the GRB was observed however between t0 + 1680 s and t0 + 3500 s. During this time interval, the data from the Fermi-LAT show a significant increase in the event rate correlated with the trigger with high significance. 5 photons were detected above 100 MeV. The highest-energy photon is a 4 GeV event which is observed 2000 seconds after the GBM trigger. The Fermi-LAT point of contact for this burst is Giacomo Vianello (email@example.com). The Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.
