Pelassa (UAH) reports on behalf of the Fermi GBM Team:\n\n\"At 23:55:58.77 UT on 13 september 2012, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 120913B (trigger 369273361 / 120913997), which\nwas also detected by the Swift/BAT (E.A. Helder et al. 2008, GCN 13763)\nThe GBM on-ground location is consistent with the Swift position.\n The angle from the Fermi LAT boresight is 66 degrees.\n\nThe GBM light curve consists of 2 peaks at T0-10 and T0+30s on top of a\nlonger plateau, with a duration (T90) of about 110 s (50-300 keV).\nThe time-averaged spectrum from T0-40.961 s to T0+98.306 s is\nbest fit by a Band function with Epeak = 163 +/- 23 keV,\nalpha = -1.19 +/- 0.06, and beta = -1.97 +/- 0.07\n(Cstat 604 for 483 d.o.f.).\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.9 +/- 0.7)E-05 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+37.632 s in the 10-1000 keV band\nis 5.0 +/- 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.\"",
