Meegan (UAH) report on behalf of the Fermi GBM Team:\n\n\"At 07:56:58.04 UT on 25 March 2017, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 170325A (trigger 512121423/170325331),\nwhich was also detected by the Swift/BAT (Palmer et al. 2017, GCN 20938).\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 60 degrees.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 0.58 s (50-300 keV).\nThe time-averaged spectrum from T0-0.064 s to T0+0.192 s is\nadequately fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.7 +/- 0.2 and\nthe cutoff energy, parameterized as Epeak, is 600 +/- 200 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(4.8 +/- 0.6)E-7 erg/cm^2. The 64-ms peak photon flux, measured\nstarting from T0 in the 10-1000 keV band, is 7.6 +/- 1.1 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
