Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\n\"At 04:18:38.88 UT on 14 May 2017, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 170514A (trigger 516428323 / 170514180).\nThe on-ground calculated location, using the GBM trigger\ndata, is\n\nRA, Dec = 122.10, -25.30\n\n(J2000 degrees, equivalent to 08h 08m, -25d 18'),\nwith an uncertainty of 2.2 degrees (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which we have characterized as a core-plus-tail model, with 90% of\nGRBs having a 3.7 deg error and a small tail suffering a larger than 10 deg\nsystematic error [Connaughton et al. 2015, ApJS, 216, 32]).\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 58 degrees.\n\nThe GBM light curve shows two distinct emission episodes\nwith a duration (T90) of about 104 s (50-300 keV).\nThe time-averaged spectrum from T0 s to T0+30 s\nand from T0+75 s to T0+100 s is adequately fit by\na power law function with an exponential\nhigh-energy cutoff. The power law index is -1.53 +/- 0.02 and\nthe cutoff energy, parameterized as Epeak, is 150 +/- 7 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.26 +/- 0.04)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+83.4 s in the 10-1000 keV band\nis 13.0 +/- 0.3 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
