Briggs (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 01:59:04.37 UT on 15 June 2010, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 100615A (trigger 298259946 / 100615083)\nwhich was also detected by the SWIFT-BAT\n(D'Elia et al. 2010, GCN 10841).\nThe GBM on-ground location is consistent with the Swift position.\nThe angle from the Fermi LAT boresight is 64 degrees.\n\nThe GBM light curve consists of 3 main pulses\nwith a duration (T90) of about 37.7 +/- 0.8 s (10-1000 keV).\nThe time-averaged spectrum from T0+0.003 s to T0+39.553 s is\nbest fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -1.34 +/- 0.04 and\nthe cutoff energy, parameterized as Epeak, is 106.20 (+7.53/-6.07) keV\n(CSTAT 989.31 for 606 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(8.64 +/- 0.17)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+9.7 s in the 8-1000 keV band\nis 8.3 +/- 0.2 ph/s/cm^2.\n\nA Band function fits the spectrum equally well (CSTAT 976.41 for 605 d.o.f.)\nwith Epeak = 85.73 (+7.82/-9.33) keV, alpha = -1.24 (+0.08/-0.06) and\nbeta = -2.27 (+0.11/-0.12).\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
