Malacaria (NASA-MSFC/USRA) and C.Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 22:09:42.72 UT on 26 August 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 200826B (trigger 620172587 / 200826923).\n\nThe on-ground calculated location, using the GBM trigger\ndata, was reported in GCN 28292.\n\nThe GBM light curve shows an exceptionally bright long GRB\nwith a duration (T90) of about 7.4 s (50-300 keV).\nThe time-averaged spectrum from T0-0.003 s to T0+ 12.544 s is\nbest fit by a Band function with Epeak = 410.3 +/- 5.6  keV,\nalpha = -0.64 +/- 0.01, and beta = -2.52 +/- 0.04\nThe event fluence (10-1000 keV) in this time interval is\n(1.414 +/- 0.006)E-04 erg/cm^2. \nThe 1.024-sec peak photon flux measured starting from T0+5.1 s in \nthe 10-1000 keV band is 110.1 +/- 0.7 ph/s/cm^2.\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/\"",
