Bhat (UAH) \nreports on behalf of the Fermi GBM Team:\n\n\"At 03:55:23.71 UT on 19 June 2010, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 100619A (trigger 298612525 / 100619015).\nwhich was also detected by the SWIFT-BAT (Cannizzo et al. 2008, GCN 10863)\nThe GBM on-ground location is consistent with the Swift position.\n \nThe angle from the Fermi LAT boresight is 117 degrees.\n\nThe GBM light curve shows 2 well separated pulses\nwith a duration (T90) of about 96.8 s (50-300 keV).\nThe time-averaged spectrum from T0-9.216 s to T0+101.378 s is\nwell fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -1.61 +/- 0.05 and\nthe cutoff energy, parameterized as Epeak, is 143.2 +/- 24.8 keV\n\n(C-stat 419 for 241 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(1.71 +/- 0.1)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+83 s in the 10-1000 keV band is 1.88 +/- 0.04 ph/s/cm^2.\n\nA Band function fits the spectrum equally well (C-stat 419 for 240 d.o.f.)\nwith Epeak= 135.3 +/- 37.1 keV, alpha = -1.60 +/- 0.07 and beta = -2.36 +/-\n0.69. \n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
