The GBM on-ground location is consistent with the Swift/UVOT afterglow candidate position (Barlow et al. 2012, GCN 13993).\n\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 229.30, DEC = +54.14 (J2000 degrees,\nequivalent to 15h 17m 12s, 54d 08' 24\"), with an uncertainty\nof 2.22 degrees (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which is currently estimated to be 2 to 3 degrees).\n\nThe angle from the Fermi LAT boresight is 37 degrees.\n\nThe GBM light curve shows/consists of several pulses\nwith a duration (T90) of about 50 s (50-300 keV).\nThe time-averaged spectrum from T0-11.3 s to T0+49.1 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.38 +/- 0.06 and\nthe cutoff energy, parameterized as Epeak, is 196 +/- 26 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(9.5 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+32 s in the 10-1000 keV band\nis 4.2 +/- 0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
