TITLE: GCN CIRCULAR NUMBER: 16555 SUBJECT: GRB 140709A: Fermi GBM detection DATE: 14/07/09 17:01:51 GMT FROM: Eric Burns at U of Alabama E. Burns (UAH) reports on behalf of the Fermi GBM Team: "At 01:13:41.38 UT on 09 July 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140709A (trigger 426561224 / 140709051). which was also detected by the Swift/BAT (L. Hagen et al., GCN 16546) The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 111 degrees. The GBM light curve consists of two main peaks with a duration (T90) of about 70s (50-300 keV). The time-averaged spectrum from T0-25 s to T0+45 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.10 +/- 0.07 and the cutoff energy, parameterized as Epeak, is 126 +/- 9 keV The event fluence (10-1000 keV) in this time interval is (8.8 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+15.0 s in the 10-1000 keV band is 5.2 +/- 0.3 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
