Piron (CNRS/IN2P3/LUPM) report on behalf of the Fermi-LAT Collaboration:\n\nOn November 16, 2020 Fermi-LAT detected high-energy emission from\nGRB 201116A, which was also detected by Fermi-GBM (trigger 627180592,\nGCN 28897).\n\nThe best LAT on-ground location is found to be\n\nRA, Dec 149.33, 0.32 (degrees, J2000)\n\nwith an error radius of 0.24 deg (90% containment, statistical error only).\nThis was 14 deg from the LAT boresight at the time of the GBM trigger:\n\nT0 = 00:49:47 UT.\n\nThe data from the Fermi-LAT show a significant increase\nin the event rate after the GBM trigger that is spatially correlated \nwith the\nGBM emission (4 degrees from the GBM location) with high significance.\nThe photon flux above 100 MeV in the time interval 0-1000s after the\nGBM trigger is (2.25+/-0.07)e-06 ph/cm2/s.\n\nThe estimated photon index above 100 MeV is -1.9 +/- 0.3.\n\nThe highest-energy photon is a 2.4 GeV event which is observed 82 \nseconds after the GBM trigger.\n\nA Swift ToO has been approved for this burst.\n\nThe Fermi-LAT point of contact for this burst is\nFrederic Piron (piron@in2p3.fr).\n\nThe Fermi-LAT is a pair conversion telescope designed to cover\nthe energy band from 20 MeV to greater than 300 GeV.\nIt is the product of an international collaboration between\nNASA and DOE in the U.S. and many scientific institutions\nacross France, Italy, Japan and Sweden.",
