Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\n\"At 10:37:36.71 UT on 8 October 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 201008A (trigger 623846261 / 201008443),\nwhich was also detected by the Swift/BAT-GUANO (DeLaunay et al. 2020, GCN 28583).\nThe Fermi GBM Final Real-time Localization is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight\nat the GBM trigger time is 60 degrees.\n\nThe GBM light curve consists of a multi-peaked emission episode\nwith a duration (T90) of about 2 s (50-300 keV).\nThe time-averaged spectrum from T0-0.26 s to T0+2.11 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff. The power law index is -0.80 +/- 0.13 and\nthe cutoff energy, parameterized as Epeak, is 166 +/- 21 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.17 +/- 0.09)E-06 erg/cm^2. The 64-ms peak photon flux measured\nstarting from T0+1.28 s in the 10-1000 keV band\nis 7.3 +/- 1.3 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/\"",
