This trigger\nresulted in an Autonomous Repoint Request (ARR) that was accepted and the\nspacecraft slewed to the GBM in-flight location. The angle from the Fermi\nLAT boresight at trigger time is 77 degrees.\n\n\nThe GBM light curve consists of a single main FRED-like peak\nwith a duration (T90) of about 4.1 s (50-300 keV).\n\nThe time-averaged spectrum from T0+0.5 s to T0+4.6 s is\nbest fit by a a Band function with Epeak = 57.8 +/- 0.6 keV,\nalpha = -1.1+/- 0.02, and beta = -2.6 +/- 0.03. The event fluence\n(10-1000 keV) in this time interval is (2.78 +/- 0.02)E-05 erg/cm^2.\nThe 1-sec peak photon flux measured starting from T0+1.76 s in the\n10-1000 keV band is 189.0 +/- 1.1 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
