Preece (UAH) report on behalf of the Fermi GBM Team:\n\n\"At 21:06:53.03 UT on 15 December 2008, the Fermi Gamma-Ray Burst  \nMonitor\ntriggered and located GRB 081215B (trigger 251068014 / 081215.880).\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 244.8, DEC = -45.3 (J2000 degrees,\nequivalent to 16h19m, -45d20'), with a statistical uncertainty of 5.9  \ndegrees\n(radius, 1-sigma containment, statistical only; there is additionally\na systematic error which is currently estimated to be 2 to 3 degrees).\nThe angle from the Fermi LAT boresight is 112 degrees.\n\nThe GBM light curve shows/consists of two peaks, each with a duration  \nof ~10 seconds, at T0\nand ~T0+80 seconds, with little emission in between.\nThe time-averaged spectrum from T0-1.3 s to T0+7.9 s is\nwell fit by a power law function with an exponential\nhigh energy cutoff. The power law index is -0.14 +/- 0.26 and\nthe cutoff energy, parameterized as Epeak, is 139 +/- 14 keV.\nThe event fluence (50-300 keV) in this time interval is\n(2.8 +/- 0.5)E-06 erg/cm^2.\n\nThe spectral and temporal analysis results presented above are  \npreliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
