GCN Circular 19732
R. Hamburg (UAH), E. Burns (UAH), and E. Bissaldi (Politecnico & INFN Bari) report on behalf of the Fermi GBM Team: "At 01:34:07.72 UT on 26 July 2016, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 160726A (trigger 491189651 / 160726065), which was also detected by the Swift/BAT (Starling et al. 2016, GCN 19731). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi-LAT boresight at the GBM trigger time is 50 degrees. The GBM light curve consists of two short peaks with a duration (T90) of about 0.7 s (50-300 keV). The time-averaged spectrum from T0-0.06 s to T0+0.77 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.0 +/- 0.1 and the cutoff energy, parameterized as Epeak, is 540 +/- 100 keV. The event fluence (10-1000 keV) in this time interval is (1.01 +/- 0.05)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0-0.06 s in the 10-1000 keV band is 5.5 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
