Collazzi (NASA/ORAU) reports on behalf of the Fermi GBM Team:\n\n\"At 22:58:57.47 UT on 18 November 2013, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 131118A (trigger 406508340 / 131118.958). The\non-ground calculated location, using the Fermi GBM trigger data,\nis RA = 349.7, Dec = -69.4 (J2000 degrees, equivalent to J2000 23h 18.8m,\n-69� 24' ), with a statistical uncertainty of 1.0 degrees (radius, 1-sigma\ncontainment, statistical only; there is additionally a systematic error which\nis currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT\nboresight is 150 degrees.\n\nDue to the high zenith angle of this burst, there may be higher than normal\nsystematic errors on this location.  This burst was also observed by Swift-BAT\n(ground analysis), Suzaku-WAM, and INTEGRAL/SPI-ACS.\n\nThe GBM light curve shows a multi-peaked event with a duration (T90)\nof about 85 s (50-300 keV). The 1.024-s peak flux during this interval is\n12.5 +/- 0.9 erg/s/cm^2 (10-1000 keV). The time-averaged spectrum\nfrom T0-13.8 to T0+99.8 s is equally well fit to a Comptonized model\nwith Epeak = 370.5 +/- 10.6, alpha = -0.89 +/- 0.03 and a Band model with\nEpeak = 366.8 +/- 12.5, alpha = -0.89 +/- 0.03, and beta = -3.4 +/- 0.6.\nBoth models yield a fluence (10-1000 keV) in this time interval \nof (9.2 +/- 0.1)E-05 erg/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
