Wilson-Hodge (NASA/MSFC) and Suzanne Foley (MPE) \nreport on behalf of the Fermi GBM Team: \n\n\"At 00:46:38.99 UT on 07 July 2010, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 100707 (trigger 300156400 / 100707.032).\n\nThe on-ground calculated location, using the GBM trigger \ndata, is RA = 351.07, DEC = -6.57 (J2000 degrees, \nequivalent to 23 h 24 m, -6 d 34 '), with an uncertainty \nof 1 degree (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 90 degrees.\n\nThe GBM light curve show a fast rise and exponential decay\nwith a duration (T90) of 82+/-1 s (50-300 keV). \nThe time-averaged spectrum from T0-0.064 s to T0+83.009 s is \nwell fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -0.91 +/- 0.02 and\nthe cutoff energy, parameterized as Epeak, is 283 +/- 7 keV\n\n(C-Statistic 529.4 for 358 d.o.f.).\n\nThe event fluence (10-1000 keV) in this time interval is \n(8.77 +/- 0.02)E-05 erg/cm^2. The 1-sec peak photon flux measured \nstarting from T0+1.152 s in the 10-1000 keV band \nis 48.3 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary; \nfinal results will be published in the GBM GRB Catalog.\"",
