Meegan\n(UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 11:04:32.93 UT on 11 July 2020, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 200711A(trigger 616158277 / 200711461),\nwhich was also detected by the Swift/BAT (Marshall et al. 2020, GCN 28078).\nThe GBM on-ground location is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 77\ndegrees.\n\nThe GBM light curve consists of a single bright pulse followed by some\nextended emission with a duration (T90) of about 29 s (50-300 keV).\nThe time-averaged spectrum from T0 s to T0+24.58 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.04 +/- 0.03 and\nthe cutoff energy, parameterized as Epeak, is 287 +/- 18 keV.\nA Band function fits equally well, with Epeak = 215 +/- 23 keV,\nalpha = -0.95 +/- 0.05 and beta = -2.04 +/- 0.10.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.510 +/- 0.042)E-05 erg/cm^2. The 1-sec peak photon flux\nmeasured starting from T0+3.64 s in the 10-1000 keV band\nis 16.3 +/- 0.3 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\nPage:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
