TITLE: GCN CIRCULAR NUMBER: 15332 SUBJECT: GRB 131014A: Fermi GBM detection DATE: 13/10/14 13:13:57 GMT FROM: Gerard Fitzpatrick at UCD G. Fitzpatrick (UCD) and S. Xiong (UAH) report on behalf of the Fermi GBM Team: At 05:09:00.20 UT on 14 October 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 131014A (trigger 403420143/131014215). High peak flux from the GRB caused GBM to issue a repoint request that reoriented the satellite to place the GRB near the LAT boresight for 2.5 hours, subject to Earth limb contraints. The on-ground calculated location, using the GBM trigger data, is RA = 101.9 , DEC = -20.0 (J2000 degrees, equivalent to 06h 47m, -20d 0.0'), with an uncertainty of 1.00 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 71.9 degrees. The GBM light curve consists of a single peak with a duration (T90) of about 3.2 s (50-300 keV). The event fluence (10-1000 keV) in this time interval is 1.9E-4 +/- 2E-7 erg/cm^2. The 1-sec peak photon flux measured starting from T0+1.3 s in the 10-1000 keV band is 311.5 +/- 1.3 ph/s/cm^2. The time-averaged spectrum from T0-1.0 s to T0+4.2 s is adequately fit by a Band function with Epeak = 318 +/- 3 keV, alpha = -0.34 +/- 0.01, and beta = -2.58 +/- 0.02 The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog.
