  "body": "Valerie Connaughton (UAH) reports on behalf of the Fermi GBM Team:\n\n\"At 22:24:55.28 UT on 12 January 2011, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 110112B (trigger 316563897 / 110112934),\nwhich was also detected by INTEGRAL IBAS in the IBIS/ISGRI data\n(Mereghetti 2011, GCN 11562).\n\nThe angle from the Fermi LAT boresight is 50 degrees.\n\nThe GBM light curve consists of a single forked peak lasting\nabout 0.256 s.\n\nThe time-averaged spectrum from T0-0.064 s to T0+0.192 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.72 � 0.20 and\nthe cutoff energy, parametrized as Epeak, is 495 � 196 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.53 � 0.49)E-07 erg/cm2.  The 64 ms peak photon flux\nmeasured starting from T0-0.064 s in the 10-1000 keV band\nis 8.7 � 1.0 ph/s/cm2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\""
