Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\n\"At 03:29:01.46 UT on 11 June 2018, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 180611A (trigger 550380546 / 180611145),\nwhich was also reported by Hurley et al. 2018 (GCN 22767).\nThe GBM location is consistent with the IPN triangulated box.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 62 degrees.\n\nThe GBM light curve shows a multipeaked emission episode\nwith a duration (T90) of about 9 s (50-300 keV).\nThe time-averaged spectrum from T0-1 s to T0+10 s is\nadequately fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.95 +/- 0.06 and\nthe cutoff energy, parameterized as Epeak, is 253 +/- 22 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.4 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0 in the 10-1000 keV band\nis 8.4 +/- 0.3 ph/s/cm^2.\n\nA Band function fits the spectrum equally well\nwith Epeak = 219 +/- 30 keV, alpha = -0.9 +/- 0.1 and\nbeta = -2.4 +/- 0.3.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
