Roberts (UCD) reports on behalf of the Fermi GBM Team:\n\n\"At 06:28:53.76 UT on the 1st of January 2015, the Fermi\nGamma-Ray Burst Monitor triggered and located GRB 150101A\n(trigger 441786536 / 150101270). The GBM on-ground location,\nusing the Fermi GBM trigger data, is consistent with the\nenhanced Swift XRT position (Goad et al. 2015, GCN 17262).\n\nThe angle from the Fermi LAT boresight is about 12 degrees.\n\nThe GBM light curve consists of a single quick pulse with\na duration (T90) of about 0.24 s (50-300 keV). The\ntime-averaged spectrum from T0-0.13 s to T0+13 s is\nadequately fit by a power law function. The power law index is\n -1.5 +/- 0.1. The event fluence (10-1000 keV) in this time\ninterval is (9.9 +/- 2.0)E-08  erg/cm^2. The 64 ms peak\nphoton flux measured starting from T0-0.1 s in the\n10-1000 keV band is 5.3 +/- 1.1 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
