The angle of the\nburst direction to the Fermi LAT boresight is 136 degrees.\n\n\nThe GBM light curve consists of multiple peaks with a duration (T90)\nof about 23 s (50-300 keV). The time-averaged spectrum from T0+0s to\nT0+23 s is well fit by a BAND function with Epeak = 109.9 +/- 10.6 keV,\nalpha = -1.0 +/- 0.1 and Beta = -2.3 +/- 0.1. The event fluence (10-1000 keV)\nin this time interval is (1.15 +/- 0.04)E-05 erg/cm^2. The 1.0-sec\npeak photon flux measured starting from T0+13.8 s in the 10-1000 keV\nband is 22.1 +/- 0.7 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
