Collazzi (NASA/ORAU) reports on behalf of the Fermi GBM\nTeam:\n\n\"At 15:12:10.85 UT on 2 December 2013, the Fermi Gamma-Ray Burst\nMonitor triggered and located GRB 131202A (trigger 407689933 / \n131202633), which was also detected by the Swift/BAT and Swift/XRT\n(Kocevski et al., GCN 15559). The GBM on-ground location is\nconsistent with the Swift/XRT position.\n\nThe angle from the Fermi LAT boresight is 86 degrees.\n\nThe GBM light curve consists of a single pulse with a duration (T90)\nof 26 s (50-300 keV). We find the 1.024-s peak flux (10 - 1000 keV),\nmeasured starting from T0-2.560, to be 1.5 +/- 0.2 ph/(s cm^2).\nThe time-averaged spectrum from T0-8.2 s to T0+11.3 s is best fit\nby a power law function with an exponential high-energy cutoff.\nThe power law index is -1.10 +/- 0.25 and the cutoff energy,\nparameterized as Epeak, is 288.4 +/- 172.0 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.6 +/- 0.4)E-06 erg/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
