Bissaldi (University and\nINFN Trieste) report on behalf of the Fermi-LAT team:\n\nOn March 23, 2014, Fermi-LAT detected high-energy emission from\nGRB 140323A, initially detected by Swift (Troja et al., GCN 16027)\nand also detected by Fermi-GBM (Yu et al., GCN 16032).\nWe note that the GBM and the Swift trigger times are different.\nHere we will use as a reference the GBM trigger time,\ni.e. 10:22:53.12 UT.\n\nThe data from the Fermi-LAT show a significant increase\nin the event rate within 10 degrees of the Swift location.\nMore than 11 photons above 100 MeV and 3 photons above 1 GeV\nare observed within 1000 seconds from the GBM trigger time.\nThe highest-energy photon is a 2.5 GeV event,\nwhich is observed ~220 seconds after the trigger.\n\nThe best LAT on-ground location is found to be\n\nRA, Dec 356.46, -79.87 (J2000)\n\nwith an error radius of 0.19 deg (90% containment, statistical\nerror only). This is 0.09 deg from the Swift/XRT localization\n(GCN 16028) and is consistent with it.\nThe source was 31 deg from the LAT boresight\nat the time of the trigger.\n\nThe Fermi-LAT point of contact for this burst is\nDaniel Kocevski (daniel.kocevski@nasa.gov).\n\nThe Fermi-LAT is a pair conversion telescope designed\nto cover the energy band from 20 MeV to greater than 300 GeV.\nIt is the product of an international collaboration\nbetween NASA and DOE in the U.S. and many scientific\ninstitutions across France, Italy, Japan and Sweden.",
