Briggs (UAHuntsville) reports on behalf of the Fermi GBM Team:\n\n\"At 22:50:04.73 UT on 23 October 2010, the Fermi Gamma-ray Burst Monitor\n(GBM) triggered and located GRB 101023A (trigger 309567006 / 101023.951).\n\nThe burst was also detected by the SWIFT-BAT (C. J. Saxton et al. 2010,\nGCN 11363).  The GBM on-ground location is consistent with the Swift\nposition.\n\nThe GBM light curve shows two major pulses, the first from 0 to 25 s\nrelative to the trigger time, the second from 45 to 100 seconds, with\nthe GRB having a T90 duration of 77 +/- 8 s (50-300 keV).\nThe spectrum from 0 to 95 s is well fit with a cutoff power law with\nan index of -1.64 +/- 0.01 and an Epeak of 277 +/- 14 keV.   The fluence\n(10-1000 keV) for the t90 time interval is (6.4 +/- 0.1) E-05 erg/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
