Foley (MPE) reports on behalf of the Fermi GBM Team:\n\n\"At 02:20:21.99 UT on 14 April 2010, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 100414A (trigger 292904423 / 100414097).\nThe Fermi Observatory executed a maneuver following this trigger and\ntracked the burst location for the next 5 hours, subject to\nEarth-angle constraints.\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 184.51, DEC = 9.65 (J2000 degrees,\nequivalent to 12 h 18 m, 09 d 39 '), 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 65 degrees.\n\nThe GBM light curve consists of one main pulse\nwith a duration (T90) of about 26.4 (+/-1.6) s (50-300 keV).\nThe time-averaged spectrum from T0+2.3 s to T0+28.9 s is\nwell fit by a power law function with an exponential\nhigh energy cutoff.  The power law index is -0.58 (+/- 0.01) and\nthe cutoff energy, parameterized as Epeak, is 627.6 (+12.5/-12.1)\nkeV (CSTAT 1075.2 for 480 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(1.29 +/- 0.02)E-4 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+22.8 s in the 8-1000 keV band\nis 18.22 +/- 0.24 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
