Hamburg (UAH)\nreports on behalf of the Fermi GBM Team:\n\n\"At 14:21:12.94 UT on 24 August 2016, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 160824B (trigger 493741276 / 160824598).\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 73, DEC = +68, with an uncertainty\nof 1 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 121\ndegrees.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 3.6 s (50-300 keV).\nThe time-averaged spectrum from T0-0.26 to T0+3.07 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.20 +/- 0.06 and\nthe cutoff energy, parameterized as Epeak, is 649.70 +/- 32.60 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.39 +/- 0.03)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+1.7 s in the 10-1000 keV band\nis 11.9 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
