Foley (MPE)\nreports on behalf of the Fermi GBM Team:\n\n\"At 11:45:23.07 UT on 01 July 2010, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 100701B (trigger 299677525 / 100701490).\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 45.49, DEC = -3.43 (J2000 degrees,\nequivalent to 03 h 02 m, -03 d 26 '), with an uncertainty\nof 1.0 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 107 degrees.\n\nThe GBM light curve consists of at least six main pulses\nwith a duration (T90) of about 27.5 (+/-0.9) s (8-1000 keV).\nThe time-averaged spectrum from T0-1.2 s to T0+32.7 s is\nwell fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -0.99 (+/-0.02) and\nthe cutoff energy, parameterized as Epeak, is 1.85 (+/-0.16) MeV\n(CSTAT 695.8 for 360 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(2.86 +/- 0.03)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+3.4 s in the 8-1000 keV band\nis 22.6 +/- 0.3 ph/s/cm^2.\n\nA Band function fits the spectrum equally well (CSTAT 689.8 for 359 d.o.f.)\nwith Epeak= 1.48 (+0.19/-0.17) MeV, alpha = -0.95 (+/-0.03) and beta =\n-2.47 (+0.18/-0.25) .\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
