Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 11:59:00.81 UT on 22 April 2016, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 160422A (trigger 483019144 / 160422499).\n\nThe trigger resulted in an Autonomous Repoint Request (ARR)\nby the GBM Flight Software owing to the high peak flux of the GRB.\nThis ARR was accepted and the spacecraft slewed to the GBM in-flight\nlocation. The initial angle from the Fermi LAT boresight to\nthe LAT location is 53 degrees. The GBM on-ground location is\nconsistent with the LAT location (Yassine et al., GCN 19329).\n\nThe GBM light curve consists of a single main peak\nwith a duration (T90) of about 12 s (50-300 keV).\nThe time-averaged spectrum from T0 s to T0+13.1 s is\nwell fit by a Band function with Epeak = 242 +/- 4 keV,\nalpha = -0.95 +/- 0.01, and beta = -2.42 +/- 0.04.\n\nThe event fluence (10-1000 keV) in this time interval is\n(8.68 +/- 0.04)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+8.0 s in the 10-1000 keV band\nis 93.8 +/- 0.6 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
