Palatiello (University \nand INFN, Trieste)\nreport on behalf of the Fermi-LAT collaboration:\n\n\nAt 05:37:56.50 UT on November 24, 2017, Fermi-LAT\ndetected high-energy emission from GRB 171124A, which was also\ndetected by Fermi-GBM (trigger 533194681 / 171124235).\n\nThe best LAT on-ground location is found to be\n\nRA, Dec = 335.52, 35.22 deg (J2000)\n\nwith an error radius of 0.18 deg (90 % containment, statistical error \nonly).\n\nThis was 19 deg from the LAT boresight at the time of the trigger.\nMore than 10 photons with Energy > 100 MeV are associated to\nthe GRB in 350 s. The highest-energy photon is a 3.5 GeV event,\nwhich is observed 4 seconds after the GBM trigger.\n\nA Swift ToO has been approved for this burst.\n\nThe Fermi-LAT point of contact for this burst\nis Francesco Longo (francesco.longo@ts.infn.it).\n\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.",
