Connaughton (USRA), and Rachel Hamburg (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\n\"At 01:34:16.04 UT on 04 August 2016, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 160804A (trigger 491967260 / 160804065),\nwhich was also detected by the Swift-BAT (Marshall et al. 2016, GCN 19761).\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 87\ndegrees.\n\nThe GBM light curve consists of single emission episode\nwith a duration (T90) of about 130 s (50-300 keV).\nThe time-averaged spectrum from T0-60 s to T0+70 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.1 +/- 0.1 and\nthe cutoff energy, parameterized as Epeak, is 74 +/- 3 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.5 +/- 0.3)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+10 s in the 10-1000 keV band\nis 4.6 +/- 0.3 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
