Ahlgren (KTH), report on behalf of the Fermi-LAT team:\n\nAt 22:17:53.73 on March 14, 2016 Fermi-LAT detected high-energy emission from GRB 160314B, which \nwas also detected by Fermi-GBM (trigger 479686676 / 160314929). \n\nThe best LAT on-ground location is found to be:\nRA, Dec (J2000) = 167.56, 45.67 \nwith an error radius of 0.65 deg (90 % containment, statistical error only). \n\nUnfortunately, the LAT was not taking data at the trigger time T0, because Fermi was just exiting the South \nAtlantic Anomaly (SAA).  Note that LAT and GBM have slightly different SAA definitions in onboard software.  \nHowever, LAT resumed data taking ~30 seconds after T0, and the GRB was 21 deg from the LAT boresight \nat that time. \n\nThe LAT data show a significant increase in the event rate that is spatially and temporally \ncorrelated with the trigger with high significance. The highest-energy photon is a 900 MeV event which is \nobserved ~630 seconds after the GBM trigger.\n\nThe Fermi-LAT point of contact for this burst is B. Ahlgren (bjornah@kth.se).\n\nThe Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater \nthan 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and \nmany scientific institutions across France, Italy, Japan and Sweden.",
