GCN Circular 12826
S. McBreen (UCD/MPE) reports on behalf of the Fermi GBM Team: "At 09:12:15.41 UT on 07 January 2012, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 120107A (trigger 347620337/120107384) which was also detected by the Fermi/LAT (Zheng and Akerlof 2012, GCN 12822). The GBM light curve consists of about six pulses with a duration (T90) of about 23 s (50-300 keV). The time-averaged spectrum from T0 s to T0+23 s is well fit by a Band function with Epeak = 188.90 (+24.90/-22.20) keV, alpha = -0.91 (+0.08/-0.07), and beta = -2.11 (+0.12/-0.19). The event fluence (10-1000 keV) in this time interval is (6.81 +/- 0.06)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+0.003 s in the 10-1000 keV band is 5.55 +/- 0.24 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
