Roberts (UCD) reports on behalf of the Fermi GBM Team:\n\n\"At 03:24:22.64 UT on the 30th of December 2014, the Fermi\nGamma-Ray Burst Monitor triggered and located GRB 141230A\n(trigger 441602665 / 141230142 ). The GBM on-ground location,\nusing the Fermi GBM trigger data, is RA = 57.0, Dec =+1.6,\nwith an uncertainty of 3.3 degrees (radius, 1-sigma\ncontainment,statistical only; there is additionally a\nsystematic error which is currently estimated to be 2 to\n3 degrees).\n\nThe angle from the Fermi LAT boresight is about 120 degrees.\n\nThe GBM light curve consists of a single FRED-like peak with\na duration (T90) of about 9.9 s (50-300 keV). The time-averaged\nspectrum from T0+0.0 s to T0+5.1 s is well fit by a power law\nfunction with an an exponential high-energy cutoff. The power\nlaw index is -1.51 +/- 0.19 and the cutoff energy, parameterized\nas Epeak, is 75 +/- 16 keV. The event fluence (10-1000 keV) in\nthis time interval is (1.2 +/- 0.1)E-06  erg/cm^2. The 1-sec peak\nphoton flux measured starting from T0+0.1 s in the 10-1000 keV\nband is 8.4 +/- 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.\"",
