Gibby (Jacobs)\nreport on behalf of the Fermi GBM Team:\n\n\"At 04:23:23.68 UT on 27 June 2015, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 150627A (trigger 457071806 / 150627183),\nwhich was also detected by the Fermi LAT (Arimoto et al., GCN 17971).\nThe GBM on-ground location is consistent with the LAT position.\n\nThe GBM trigger resulted in an Autonomous Repoint Request (ARR) \nthat was accepted and the spacecraft slewed to the GBM in-flight \nlocation. At the GBM trigger time, the angle of the LAT localization \nto the LAT boresight is 75 deg.\n\nThe GBM light curve consists of multiple pulses\nwith a duration (T90) of about 65 s (50-300 keV).\nThe time-averaged spectrum from T0-3.072 s to T0+92.161 s is\nbest fit by a Band function with Epeak = 233 +/- 5 keV,\nalpha = -1.04 +/- 0.01, and beta = -2.18 +/- 0.02.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.90 +/- 0.01)E-4 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+59.521 s in the 10-1000 keV band\nis 65.2 +/- 0.6 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
