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 55 degrees.\n\n\nThe GBM light curve shows a bright single pulse with a duration (T90)\nof about 22.3 s (50-300 keV). The time-averaged spectrum from\nT0+3.3 s to T0+25.6 s is best fit by a Band function with\nEpeak = 311 +/- 14 keV, alpha = -0.72 +/- 0.02, and beta = -1.85 +/- 0.03.\n\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.73 +/- 0.05)E-05 erg/cm^2. The 1.024-sec peak photon flux\nmeasured starting from T0+11.1 s in the 10-1000 keV band\nis 33.5 +/- 0.5 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"\n\n\n���\nSent from Mailbox",
