The T90 is about 44 s (50-300 keV).\nThe time-averaged spectrum from T0-1 s to T0+131 s is\nbest fit by a Band function with Epeak = 973 +/- 35 keV,\nalpha = -0.94 +/- 0.01, and beta = -2.40 +/- 0.04.\nThis spectrum is typical of a bright, hard GRB, and would be \nhighly unusual for an X-ray transient (Bozzo et al. 2012, GCN 13435).\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.942 +/- 0.002)E-04 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+95 s in the 10-1000 keV band\nis 26.7 +/- 0.6 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
