Meegan (UAH) report on\nbehalf of the Fermi GBM Team:\n\n\"At 12:48:30.03 UT on 14 September 2020, the Fermi Gamma-Ray Burst\nMonitor (GBM) triggered and located GRB 200914A (trigger 621780515 /\n200914534) which was also detected by INTEGRAL (S. Mereghetti et al.,\nGCN 28419). The GBM on-ground location is consistent with the INTEGRAL\nposition. The on-ground calculated location, using the GBM trigger\ndata, is provided in GCN 28417.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 62 degrees.\n\nThe GBM light curve shows a long GRB with multiple features with a\nduration (T90) of about 65 s (50-300 keV). The time-averaged spectrum\nfrom T0 + 1.1 s to T0 + 24.6 s is best fit by a power law function\nwith an exponential high-energy cutoff.  The power law index is -0.89\n+/- 0.03 and the cutoff energy, parameterized as Epeak, is 1260 +/-\n140 keV.\n\nThe event fluence (10-1000 keV) in this time interval is (9.80 +/-\n0.71)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from\nT0 + 1.95 s in the 10-1000 keV band is 7.9 +/- 0.2 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
