This ARR was accepted and the spacecraft slewed to the GBM in-flight\nlocation. The initial angle from the Fermi LAT boresight to\nthe best location is 62 degrees.\n\nThe GBM light curve consists of multiple peaks\nwith a duration (T90) of about 114 s (50-300 keV).\nThe time-averaged spectrum from T0-0.5 s to T0+110 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.79 +/- 0.02 and\nthe cutoff energy, parameterized as Epeak, is 54.5 +/- 2.6 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.63 +/- 0.06)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+27.7 s in the 10-1000 keV band\nis 16.8 +/- 0.3 ph/s/cm^2.\n\nA Band function fits the spectrum equally well\nwith Epeak = 50.8 +/- 3.1 keV, alpha = -1.75 +/- 0.03 and beta = -2.47 +/- 0.14.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
