The angle from the Fermi LAT boresight\nis 93 degrees.\n\nThe high peak flux from the GRB caused GBM to issue an autonomous\nrapid repoint (ARR) maneuver but to an unreliable sky position \naccording to the flight software calculation. \n\nThis burst was also independently detected by INTEGRAL SPI-ACS.\n\nThe GBM light curve shows a multi-peaked feature with a duration (T90)\nof about 52 s (50-300 keV). The time-averaged spectrum from T0+0.003 s\nto T0+65.537 s is well fit by a Band function with\nEpeak = 435 +/- 11 keV, alpha = -1.14 +/- 0.01, and\nbeta = -2.05 +/- 0.02.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.034 +/- 0.007)E-04 erg/cm^2. The 1.024 s peak photon flux measured\nstarting from T0+9.15 s in the 10-1000 keV band\nis 62.14 +/- 0.58 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
