GRB 200716C: Fermi GBM detection

"At 22:57:41.18 UT on 16 July 2020, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 200716C (trigger 616633066 / 200716957) which was also detected by the Swift (Ukwatta et al., GCN 28124), Fermi-LAT (Ohno et al., GCN 28130). The GBM on-ground location is consistent with both the Swift and Fermi-LAT positions. The angle from the Fermi LAT boresight at the GBM trigger time is 37 degrees. The GBM light curve shows two overlapping pulses with a duration (T90) of about 5.3 s (50-300 keV). The time-averaged spectrum from T0-0.26 s to T0+4.9 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.07 +/- 0.03 and the cutoff energy, parameterized as Epeak, is 716 +/- 97 keV. The event fluence (10-1000 keV) in this time interval is (9.57 +/- 0.25)E-6 erg/cm^2. The 1-sec peak photon flux measured starting from T0 + 64 ms in the 10-1000 keV band is 19.3 +/- 0.3 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/"
