Because the burst \nwas close to the Earth's limb, this maneuver was delayed, placing the \nGRB position near the LAT boresight starting about 1000 s after the GBM trigger time.\n\nThe GBM light curve shows a strong central  pulse with fainter wings\nwith a duration (T90) of about 50 s (50-300 keV). The time-averaged\nspectrum from T0-3 to T0+57 s is best fit by a Band function with Epeak = \n174 +/- 7 keV, alpha = -1.17 +/- 0.03, and beta = -2.31 +/- 0.03.\n\nThe fluence (10-1000 keV) in this time interval is (1.1 +/- 0.007)E-4 erg/cm^2.\nThe 1-sec peak photon flux measured starting from T0+29.1 s in the 10-1000 keV band\nis 62 +/- 2 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
