Jenke (UAH) report on behalf of the Fermi GBM\nTeam:\n\nAt 02:04:53.49 UT on 05 November 2013, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 131105A (trigger 405309896/131105087), which\nwas also detected by Swift (Cummings et al., GCN 15446) and Konus-Wind\n(Golenetskii et al, GCN 15452).  The GBM on-ground location is consistent\nwith the Swift/XRT position (Osborne et al., GCN 15448). The angle from\nthe Fermi LAT boresight is 37 degrees.\n\nThe GBM light curve consists of a multiple-peak structure with a duration\n(T90) of about 112 s (50-300 keV). The time-averaged spectrum from\nT0-3 s to T0+121 s is adequately fit by a Band function with Epeak =\n203.9 +/- 31.1 keV, alpha = -1.2 +/- 0.1, and beta = -1.8 +/- 0.1.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.9 +/- 0.1)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+108 s in the 10-1000 keV band is 8.4 +/- 0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.",
