TITLE: GCN CIRCULAR NUMBER: 16599 SUBJECT: GRB 140716A: A Fermi GBM Detection DATE: 14/07/17 00:54:25 GMT FROM: Peter Jenke at MSFC P. Jenke (UAH) and H.-F. Yu (MPE) report on behalf of the Fermi GBM Team: "At 10:27:57.66 UT on July 16 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140716A (trigger 427199280/140716436), which was also detected by Swift (J. R. Cummings et al. 2014, GCN 16596). The GBM on-ground location, using the Fermi GBM trigger data, is consistent with the Swift/BAT location. The angle of the burst direction to the Fermi LAT boresight is 137 degrees. The GBM light curve consists of one FRED-like short peak near T0 and a longer double peak at ~T0+100s with a duration (T90) of about 106 s (50-300 keV). The time-averaged spectrum from T0+89s to T0+108s is well fit by a Band function with Epeak = 92 +/- 13 keV, Alpha = -0.8 +/- 0.2 and Beta = -2.07 +/- 0.07. The event fluence (10-1000 keV) in this time interval is (1.03 +/- 0.04)E-05 ergs/cm^2. The 1.0-sec peak photon flux measured starting from T0+100s in the 10-1000 keV band is 11.3 +/- 0.6 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
