Bhat(UAHuntsville)\nreports on behalf of the Fermi GBM Team:\n\n\"At 19:37:43.96UT on 10 September 2010, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 100910A (trigger 305840265 / 100910818).\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 238.1, DEC = -34.62 (J2000 degrees,\nequivalent to 15 h 52.4 m, -34 d 37'), with an uncertainty\nof 1.0 degrees (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which is currently estimated to be 2 to 3 degrees).\n \nThe angle from the Fermi LAT boresight is 51 degrees.\n\nThe GBM light curve consists of 4 pulses\nwith a duration (T90) of about 14.6 s (50-300 keV).\nThe time-averaged spectrum from T0-3.2 s to T0+18.3 s is\nbest fit by a Band function with Epeak = 143 +/- 7.0 keV,\nalpha = -0.92 +/- 0.04, and beta = -2.26 +/- 0.08\n\n(C-stat 1038 for 733 d.o.f.).\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.48 +/- 0.02)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+8.576 s in the 10-1000 keV band\nis 23.35 +/- 0.24 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
