Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 01:57:44.60 UT on 18 July 2018, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 180718A (trigger 553571869 / 180718082),\nwhich was also detected by the INTEGRAL SPI-ACS and subsequently\nlocalized by IPN. Ground analysis of the Swift/BAT data revealed\na detection consistent with the IPN annulus (GCN 22959).\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 61\ndegrees.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 0.08 s (50-300 keV).\nThe time-averaged spectrum from T0-0.06 s to T0+0.02 s is\nadequately fit by a Band function with Epeak = 187 +/- 61 keV,\nalpha = -0.2 +/- 0.4, and beta = -2.3 +/- 0.5.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.3 +/- 0.3)E-07 erg/cm^2. The 64-ms peak photon flux measured\nstarting from T0-0.05 s in the 10-1000 keV band\nis 9 +/- 1 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
