Moretti (MPP Munich) \nreport on behalf of the Fermi-LAT team: \n\nAt 18:45:36.71 on 2015-07-24, Fermi-LAT detected high-energy emission from GRB 150724B, \nwhich was also detected by Fermi-GBM (trigger 459456340/150724782). \n\nThe best LAT on-ground location is found to be\n\nRA, Dec = 351.92, 3.67 (J2000) \n\nwith an error radius of 0.3 deg (90% containment, systematic error only). This was 58 deg \nfrom the LAT boresight at the time of the trigger.\n\nThe data from the Fermi-LAT show a ~5 sigma increase in the event rate within 7 degrees \nof the GBM location after the GBM trigger that is spatially and temporally correlated with the \nGBM emission. More than 11 photons above 100 MeV and 1 photons above 1 GeV were \nobserved within 300 seconds. The highest-energy photon is a 2 GeV event which is \nobserved ~50 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 Elisabetta Bissaldi (elisabetta.bissaldi@ba.infn.it). \n\nThe Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV \nto greater than 300 GeV. It is the product of an international collaboration between NASA and \nDOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.",
