Ahlgren (KTH)\n\nreport on behalf of the Fermi-LAT team:\n\nAt 19:00:50.58 on October, 10, 2017 Fermi-LAT detected high-energy emission from GRB 171010A, which was also detected by Fermi-GBM (trigger 529354855 / 171010792). \n\nThe best LAT on-ground location is found to be:\n RA, Dec = 66.74, -10.53 (J2000) \n with an error radius of 0.20 deg (90 % containment, statistical error only). \n\nThe GRB was outside the LAT field of view at the time of the GBM trigger and triggered an autonomous repoint of the spacecraft.\n\nThe data from the Fermi-LAT show a significant increase in the event rate that is spatially correlated with the trigger with high significance. \n\nThe highest-energy photon is a 7 GeV event which is observed 768 seconds after the GBM trigger.\n\nA Swift ToO has been requested for this burst.\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 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.",
