Jenke (UAH) reports on behalf of the Fermi GBM Team:\n\n\"At 07:08:57.40 UT on December 22 2014, the Fermi Gamma-Ray Burst \nMonitor triggered and located \nGRB 141222A (trigger 440924940/141222298), which was also detected\nby  Fermi/LAT (J. McEnery et al. 2014, GCN 17218).\nThe GBM on-ground location, using the Fermi GBM trigger data, is consistent with\nthe Fermi/LAT location.\n\nThe angle of the burst direction to the Fermi LAT boresight is \n46 degrees.\n\nThe GBM light curve consists of a narrow peak followed by a broad peak with a tail.\nThe duration (T90) is about 2.4 s (50-300 keV).\nThe time-averaged spectrum from T0-0.06 s to T0+1.41 s is\nadequately fit by a Band function with Epeak = 2427 +/- 580 keV,\nAlpha =-1.49 +/- 0.01 and Beta = -1.74 +/- 0.05.\n\nThe event fluence (10-1000 keV) in this time interval is\n(8.16 +/- 0.08)E-06 erg/cm^2. The 64 ms peak photon flux measured\nstarting from T0+0.64 s in the 10-1000 keV band\nis 121 +/- 3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
