GCN Circ. 10401).\n\nThe angle from the Fermi LAT boresight is 15 degrees.\n\nThe GRB duration (T90) is about 2.30+/-0.14 s (8-1000 keV).\nThe time-averaged spectrum from T0-0.51 s to T0+0.26 s is\nadequately fit by a power law with an index of -1.62+/-0.06\n(Castor C-stat 394 for 363 d.o.f.).\nIt is also adequately fit by a power law function with an exponential\nhigh energy cutoff. The power law index is -1.15 +/- 0.20 and\nthe cutoff energy, parameterized as Epeak, is 159.30 +/- 45.10 keV\n(Castor C-stat 389 for 362 d.o.f.).\n\nThe event fluence (8-1000 keV) in the T90 time interval is\n(3.81+/-0.06)E-7 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-0.7 s in the 8-1000 keV band is 3.16 +/- 0.22 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
