Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 14:39:59.72 UT on 12 May 2019, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 190512A (trigger 579364804 / 190512611)\nwhich was also detected by the Swift/BAT\n(Bernardini et al. 2019, GCN 24501)\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 24 degrees.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 28 s (50-300 keV).\nThe time-averaged spectrum from T0-4.1 s to T0+27.7 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.4 +/- 0.2 and\nthe cutoff energy, parameterized as Epeak, is 110 +/- 25 keV\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.4 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+3.13 s in the 10-1000 keV band\nis 2.0 +/- 0.3 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,\nplease visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/",
