The GBM on-ground location is consistent with the Fermi flight��\nsoftware position.\n\nThe angle from the Fermi LAT boresight is 93 degrees.\n\nThe GBM light curve consists of single peak with a duration (T90) of about\n32 s (50-300 keV). The time-averaged spectrum from T0+11 s to T0+43 s is\nwell fit by Band function parameterized as Ep=483+/-22 keV,��\nalpha=-0.82+/-0.03 and beta=-2.4+/-0.1.��\n\nThe event fluence (10-1000 keV) in this time interval is\n(6.314+/-0.067)E-05 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+29 s in the 10-1000 keV band is ��19.5+/-0.6 ph/s/cm^2.\n\nThe burst spectrum may be contaminated by solar flare activity that is��\ndetected at energies below ~20 keV in many of the same GBM detectors.��\nAlthough the solar emission has several peaks, the first of which is ��\naround T0+130 s, it may have significant overlap with the time of the\nburst.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.���",
