Arimoto (Tokyo Tech),\nreport on behalf of the Fermi-LAT team:\n\nAt 18:35:05.35 on May 14, 2015, Fermi-LAT detected high-energy emission from GRB 150514A, which was also detected by Fermi-GBM (trigger 453321308).\n\nThe best LAT on-ground location is found to be\n\nRA, Dec = 74.85, -60.91 (J2000)\n\nwith an error radius of 0.12 deg (90% containment, statistical error only). This position was 40 deg from the LAT boresight at the time of the trigger.\n\nThe data from the Fermi-LAT show a significant increase in the event rate that is spatially and temporally correlated with the GBM emission with high significance. The LAT localization relies heavily on the detection of a single 6.5 GeV event at T0 + 400s, roughly 2.2 deg from the final GBM position. The GRB was observable from T0 to T0 + 600 s, before the spacecraft entered the South Atlantic Anomaly, where data gathering is disabled.\n\nThe Fermi-LAT point of contact for this burst is Makoto Arimoto (arimoto@hp.phys.titech.ac.jp<mailto:arimoto@hp.phys.titech.ac.jp>).\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.",
