The GBM on-ground location is consistent with the Swift\nposition. The angle from the Fermi LAT boresight is 86 degrees.\n\nThe GBM light curve consists of a single pulse,\nwith a duration (T90) of about 7.6 s (50-300 keV).\nThe time-averaged spectrum from T0-1.0 s to T0+4.9 s is\nadequately fit by a power law function with an exponential\nhigh-energy cutoff.  The power-law index is -0.85 +/- 0.09 and\nthe cutoff energy, parameterized as Epeak, is 141.6 +/- 12.2 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.5 +/- 0.1)E-6 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+0.6 s in the 10-1000 keV band\nis 7.1 +/- 0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
