Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 03:19:53.74 UT on 10 May 2015, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 150510A (trigger 452920796 / 150510139),\nwhich was also detected by the Fermi LAT (Vianello et al. 2015,\nGCN 17805). The GBM on-ground location is marginally consistent\nwith the LAT position.\n\nThe angle of the burst direction to the Fermi LAT boresight was\n55 degrees. The trigger resulted in an Autonomous Repoint Request\n(ARR) that was accepted and the spacecraft slewed to the GBM\nin-flight location.\n\nThe GBM light curve shows a FRED profile\nwith a duration (T90) of about 52 s (50-300 keV).\nThe time-averaged spectrum from T0+0.256 s to T0+52.480 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.04 +/- 0.01 and\nthe cutoff energy, parameterized as Epeak, is 1651 +/- 58 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(9.32 +/- 0.05)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+0.064 s in the 10-1000 keV band\nis 32.0 +/- 0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
