GCN Circular 19932
P Veres (UAH), A von Kienlin (MPE) and C Meegan (UAH) report on behalf of the Fermi GBM Team: "At 11:30:19.286 UT on 17 September 2016, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 160917A (trigger 495804623 / 160917479). which was also detected by the Swift/BAT ��� ��� (Racusin et al., GCN 19926). ��� ��� The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight at the GBM trigger time is 46 degrees. The GBM light curve consists of a single peak with a duration (T90) of about 47 s (50-300 keV). The time-averaged spectrum from T0 to T0+14.1 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.00 +/- 0.05 and the cutoff energy, parameterized as Epeak, is 1604 +/- 357 keV. The event fluence (10-1000 keV) in this time interval is (7.2 +/- 0.3)E-6 erg/cm^2. The 1-sec peak photon flux measured starting from T0 in the 10-1000 keV band is 5.1 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
