The GBM on-ground location is consistent with the Swift\nposition.\n\nThe angle from the Fermi LAT boresight to the best location is 52 degrees.\n\nThe GBM light curve consists of multiple, weak emission episodes\nwith a duration (T90) of about 97 s (50-300 keV).\nThe time-averaged spectrum from T0-3.6 s to T0+40.4 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.97 +/- 0.25 and\nthe cutoff energy, parameterized as Epeak, is 61.7 +/- 7.3 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.4 +/- 0.1)E-6 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-0.2 s in the 10-1000 keV band\nis 3.3 +/- 0.2 ph/s/cm^2.\n\nA Band function fits the spectrum equally well\nwith Epeak = 51 +/- 11 keV, alpha = -0.67 +/- 0.51 and beta = -2.51 +/- 0.36.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
