Meegan (both UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 20:56:48.17 UT on 27 March 2020, the Fermi Gamma-Ray Burst Monitor\n(GBM) triggered\nand located GRB 200327A (trigger 607035413 / 200327873) which was also\ndetected by AGILE-MCAL (Ursi et al., GCN 27461) and localized by IPN (Svinkin\net al., GCN 27463). The GBM on-ground location is consistent with the IPN\nposition.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 104\ndegrees.\n\nThe GBM light curve consists of two pulses with a duration (T90) of about\n0.64 s (50-300 keV). The time-averaged spectrum from T0-64 ms to T0+192 ms\nis best fit by a power law function with an exponential high-energy\ncutoff.  The power law index is -0.60 +/- 0.09 and the cutoff energy,\nparameterized as Epeak, is 1100 +/- 180 keV.\n\nThe event fluence (10-1000 keV) in this time interval is (1.53 +/- 0.06)E-6\nerg/cm^2. The 64 ms peak photon flux measured starting from T0+64 ms in the\n10-1000 keV band is 19.2 +/- 1.4 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/\"",
