TITLE: GCN CIRCULAR NUMBER: 16014 SUBJECT: GRB 140320A: Fermi GBM detection DATE: 14/03/20 22:12:14 GMT FROM: George A. Younes at USRA/NASA/MSFC G. Younes (USRA/MSFC), V. Connaughton (UAH), C. Meegan (UAH), and A. von Kienlin (MPE) report on behalf of the Fermi GBM Team: "At 02:12:46.11 UT on 20 March 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140320A (trigger 416974369/140320092), which was also detected by Swift (Cannizzo et al. 2014, GCN 16000). The GBM on-ground location, using the Fermi GBM trigger data, is consistent with the Swift/BAT location. The angle to the Fermi LAT boresight is 24 deg. using the Swift location. The GBM light curve consists of a single pulse with a duration (T90) of 1 s (50-300 keV). The time-averaged spectrum from T0-0.32 to T0+0.704 s is well fit by a simple power law function with index of -1.5 +/- 0.1. The event fluence (10-1000 keV) in this time interval is (4.0 +/- 0.5) E-07 erg/cm^2. The 0.064-sec peak photon flux measured starting from T0-0.128 s in the 10-1000 keV band is 5.0 +/- 1.0 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
