GCN Circular 15011
S. Foley (UCD) and C. Meegan (UAH) report on behalf of the Fermi GBM Team: "At 10:36:53.59 UT on 16 July 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 130716A (trigger 395663816 / 130716442) which was also detected by the Swift/BAT (Cummings et al. 2013, GCN 15006). The GBM on-ground location is consistent with the Swift position. The GBM light curve consists of two overlapping pulses with a duration (T90) of about 0.8 s (50-300 keV). The time-averaged spectrum from T0-0.256 s to T0+0.576 s is adequately fit by a power law function with an exponential high-energy cutoff. The power law index is -0.23 (+0.28/-0.24) and the cutoff energy, parameterized as Epeak, is 635 (+184/-112) keV. The event fluence (10-1000 keV) in this time interval is (9.2 +/- 0.7)E-07 erg/cm^2. The 64-msec peak photon flux measured starting from T0+0.256 s in the 10-1000 keV band is 6.2 +/- 0.9 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
