Meegan (UAH) report on behalf of the Fermi GBM Team:\n\n\n\"At 05:59:11.92 UT on 11 May 2017, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 170511A (trigger 516175156 / 170511249),\nwhich was also detected by MAXI/GSC (Takao et al. 2017, GCN 21137)\nand by the CALET GBM (Yamaoka et al. 2017, GCN 21146).\nThe GBM on-ground location is consistent with the MAXI position.\nThe angle from the Fermi LAT boresight at the GBM trigger time is 85 degrees.\n\nThe GBM light curve consists of multiple peaks\nwith a duration (T90) of about 40 s (50-300 keV).\nThe time-averaged spectrum from T0 to T0+40 s is\nbest fit by a Band function with Epeak = 82 +/- 3 keV,\nalpha = -0.90 +/- 0.03, and beta = -2.41 +/- 0.05.\nThe event fluence (10-1000 keV) in this time interval is\n(2.80 +/- 0.04)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+34.5 s in the 10-1000 keV bandbis 30.1 +/- 0.5 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
