Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 22:20:25.30 UT on 11 July 2017, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 170711A (trigger 521504430 / 170711931)\nwhich was also detected by the Swift/BAT\n(V. D'Elia et al. 2017, GCN 21321)\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 32\ndegrees.\n\nThe GBM light curve shows one spike\nwith a duration (T90) of about 12 s (50-300 keV).\nThe time-averaged spectrum from T0-2.6 s to T0+10.8 s is\nwell fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.5 +/- 0.1 and\nthe cutoff energy, parameterized as Epeak, is 155 +/- 34 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.6 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+0.3 s in the 10-1000 keV band\nis 7.2 +/- 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.\"",
