Meegan (all UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 09:07:25.03 UT on 16 February 2020, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 200216A (trigger 603536850 / 200216380)\nwhich was also detected via Swift ground analysis (DeLaunay et al. 2020,\nGCN 27107)\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 68\ndegrees.\n\nThe GBM light curve consists of a single bright pulse followed by\nsome extended emission with a duration (T90) of about 8.0 s (10-1000 keV).\nThe time-averaged spectrum from T0-5.0 s to T0+2.5 s is best fit by\na power law function with an exponential high-energy cutoff.\nThe power law index is 0.9 +/- 0.9 and\nthe cutoff energy, parameterized as Epeak, is 180.0 +/- 34.0 keV\n\nThe event fluence (10-1000 keV) in this time interval is\n(4.4 +/- 0.9)E-07 erg/cm^2.\nThe 1-sec peak photon flux measured starting from T0-4.16 s\nin the 10-1000 keV band is 0.92 +/- 0.1 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/\"",
