Troja et al. 2014, GCN 16311).\nThe GBM on-ground location, using the Fermi GBM trigger data,\nis consistent with the Swift/BAT location.\n\nThe GBM light curve consists of one main episode with a total\nduration (T90) of about 11.5 s (50-300keV). The time-averaged\nspectrum from T0-0.864 s to T0+10.400 s is well fit\nby a power law function with an exponential high-energy cutoff.\nThe power law index is -1.04 +/- 0.08 and the cutoff energy,\nparameterized as Epeak, is 273 +/- 44 keV.\n\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.99 +/- 0.21)E-06 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0-0.10 s in the 10-1000 keV band is 3.9 +/- 0.2 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
