Wood\n(NASA/MSFC) report on behalf of the Fermi GBM Team:\n\n\"At 03:18:31.74 UT on 25 March 2020, the Fermi Gamma-Ray Burst Monitor\n(GBM) triggered\nand located GRB 200325A (trigger 606799116 / 200325138)\nwhich was also detected by the Swift/BAT (GCN 27444). The Fermi GBM Final\nReal-time Localization (GCN 27434) is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 107\ndegrees.\n\n\nThe GBM light curve consists of a single peak with a duration (T90) of\nabout 1 s (50-300 keV). The time-averaged spectrum from T0-0.1 s to T0+1.2\ns is\nbest fit by a power law function with an exponential high-energy cutoff.\nThe power law index is -0.64 +/- 0.11 and the cutoff energy, parameterized\nas Epeak, is 913 +/- 192 keV.\n\nThe event fluence (10-1000 keV) in this time interval is  (2.49 +/-\n0.12)E-6 erg/cm^2. The 64 ms peak photon flux measured starting from T0 +\n256 ms in the 10-1000 keV band is 9.6 +/- 1.5 ph/s/cm^2.\n\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\nPage:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
