Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 17:33:54.33 UT on 20 October 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 201020B (trigger 624908039 / 201020732).\nThe Fermi GBM Final Real-time Localization was reported in GCN 28702.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 69 degrees.\n\nThe GBM light curve shows multiple peaks around\nthe bright, main peak.\nThe duration (T90) is about 16 s (50-300 keV).\nThe time-averaged spectrum from T0-5.1 s to T0+23.5 s is\nbest fit by a Band function with Epeak = 136.9 +/- 3.4 keV,\nalpha = -0.71 +/- 0.02, and beta = -2.20 +/- 0.03\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.929 +/- 0.040)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+9.4 s in the 10-1000 keV band\nis 43.7 +/- 0.4 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/\"",
