Malacaria (NASA-MSFC/USRA)\nreport on behalf of the Fermi GBM Team:\n\n\"At 00:00:56.75 UT on 4 November 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 201104A (trigger 626140861 / 201104001,\nwhich was also detected by the Fermi-LAT (Ohno et al. 2020, GCN 28828) \nand AGILE (Ursi et al. 2020, GCN 28829).\nThe GBM on-ground location is consistent with the LAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 57 degrees.\n\nThe GBM light curve shows a bright emission episode\nwith a duration (T90) of about 8.4 s (50-300 keV).\nThe time-averaged spectrum from T0 to T0+9 s is\nbest fit by a Band function with Epeak = 1140 +/- 130 keV,\nalpha = -0.76 +/- 0.04, and beta = -2.24 +/- 0.17.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.55 +/- 0.03)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0 in the 10-1000 keV band\nis 12.1 +/- 0.3 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/\"",
