Roberts (UCD) reports on behalf of the Fermi GBM Team:\n\n\"At 10:18:02.36 UT on the 6th of September 2014, the Fermi Gamma-Ray\nBurst Monitor triggered and located GRB 140906B\n(trigger 431691485/140906429). The trigger resulted in an Autonomous\nRepoint Request (ARR) that was accepted. The GBM on-ground location\nis consistent with the Fermi flight software position.\n\nThe on-ground calculated location, using the GBM trigger data, is\nRA = 187.09, DEC = +1.02 (J2000 degrees, equivalent to\n +16h 33m, +49d 30'), with an uncertainty of 2 degrees (radius,\n1-sigma containment, statistical only; there is additionally a\nsystematic error which is currently estimated to be 2 to 3 degrees).\n\nThe angle from the Fermi LAT boresight is 47 degrees.\n\nThe GBM light curve consists of several bright emission episodes,\nwith a duration (T90) of about 23 seconds (50-300 keV). The\ntime-averaged spectrum from T0+0 s to T0+23 s is well fit by a\npower law function with an exponential high-energy cutoff. The power\nlaw index is -1.4 +/- 0.1 and the cutoff energy, parameterized as\nEpeak, is 330 +/- 48 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(9.91 +/- 0.07)E-06 erg/cm^2. The 1.024-sec peak photon flux\nmeasured starting from T0+15 s in the 10-1000 keV band is\n11.0+/-0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
