Racusin (NASA/Goddard), report on behalf of the Fermi-LAT\nteam:\n\nThe Fermi Large Area Telescope (LAT) detected emission from GRB\n131216A, also detected by GBM (trigger 408851795/131216081) at T0 =\n01:56:32.06 UT on December 16, 2013.\n\nThe GBM location was initially inside the LAT field of view at an\nangle of 44 degrees to the LAT boresight and triggered an autonomous\nrepoint of the spacecraft. However, LAT did not collect data while in\nthe South Atlantic Anomaly (SAA) from T0+200 to T0+800 s. No\nsignificant excess is seen using standard analysis procedures.\n\nUsing the LAT Low Energy (LLE) event selection, over 120 counts above\nbackground were detected within a 0.3 s interval coinciding with the\ntime of the GBM emission. This data selection has insufficient spatial\nresolution to provide a reliable LAT localization. Since an excess of\nevents were not seen using the standard analysis selection, this\ndetection is likely due to low energy gamma-rays (below 100 MeV).\n\nThe Fermi LAT point of contact for this burst is Peter Veres  (puv2@psu.edu).\n\nThe Fermi LAT is a pair conversion telescope designed to cover the\nenergy band from 20 MeV to greater than 300 GeV. It is the product of\nan international collaboration between NASA and DOE in the U.S. and\nmany scientific institutions across France, Italy, Japan and Sweden.",
