McBreen (UCD/MPE)\nreport on behalf of the Fermi GBM Team: \n\n\n\"At 04:54:00.25 UT on 22 December 2008, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 081222 (trigger 251614441 / 081222204),\nwhich was also detected by the Swift-BAT (Grupe et al., GCN Circular 8691\nand Fenimore et al., GCN Circular 8709).\n \nThe angle from the Fermi LAT boresight is 50 degrees.\n\nThis burst was also independently detected by INTEGRAL SPI-ACS.\n\nThe GBM light curve consists of a main pulse with a\nduration (T90) of about 30 s (8-1000 keV) and T50\nof about 10 s (8-1000 keV). \n\nThe time-averaged spectrum from T0 to T0+11.52 s is \nbest fit by a Band function with Epeak = 134 +/- 9,\nalpha = -0.55 +/- 0.07 and beta  = -2.10 +/- 0.06.\n\nThe event fluence (8-1000 keV) in this time interval is \n(1.35 +/- 0.08)E-05 erg/cm^2. The 1-sec peak photon flux \nmeasured starting from T0+3.3 s in the 8-1000 keV band\nis 14.8 +/- 1.4 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary; \nfinal results will be published in the GBM GRB Catalog.\"",
