Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 18:07:05.06 UT on 15 July 2018, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 180715A (trigger 553370830 / 180715755)\nwhich was also detected by the Swift/BAT (Ukwatta et al. 2018, GCN 22947).\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 75\ndegrees.\n\nThe GBM light curve shows a single structured peak\nwith a duration (T90) of about 0.7 s (50-300 keV).\nThe time-averaged spectrum from T0-0.19 to T+0.51 s is\nadequately fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.14 +/- 0.21 and\nthe cutoff energy, parameterized as Epeak, is 852 +/- 182 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.7 +/- 0.1)E-06 erg/cm^2. The 64-ms peak photon flux measured\nstarting from T0-0.064s in the 10-1000 keV band\nis 8.4 +/- 1.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
