Yu (MPE) reports on behalf of the Fermi GBM Team:\n\n\"At 04:54:50.85 UT on 14 Mar 2015, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 150314A (trigger 448001693 / 150314205),\nwhich was also detected by the Swift (Hagen et al. 2015, GCN 17573)\nand Fermi LAT (Axelsson et al. 2015, GCN 17576). The GBM on-ground\nlocation is consistent with the Swift position. The trigger resulted\nin an Autonomous Repoint Request (ARR) that was accepted and the\nspacecraft slewed to the GBM in-flight location. The initial angle\nfrom the Fermi LAT boresight is about 50 degrees.\n\nThe GBM light curve shows a bright single pulse with a duration (T90)\nof about 10.7 s (50-300 keV). The time-averaged spectrum from\nT0+0.002 s to T0+13.472 s is best fit by a Band function with\nEpeak = 311 +/- 5 keV, alpha = -0.60 +/- 0.01, and beta = -2.32 +/- 0.04.\n\nThe event fluence (10-1000 keV) in this time interval is\n(8.53 +/- 0.04)E-05 erg/cm^2. The 1.024-sec peak photon flux\nmeasured starting from T0+2.144 s in the 10-1000 keV band\nis 67.1 +/- 0.5 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
