TITLE: GCN CIRCULAR NUMBER: 14039 SUBJECT: GRB 121202A: Fermi GBM observation DATE: 12/12/02 18:14:21 GMT FROM: David Tierney at UCD D. Tierney (UCD) reports on behalf of the Fermi GBM Team: "At 04:20:09.17 UT on 02 December 2012, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 121202A (trigger 376114812 / 121202181) which was also detected by the Swift/BAT (Oates et al. 2012, GCN 14032) The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 62 degrees. The GBM light curve consists of a single weak pulse with a duration (T90) of 17.7 +/- 1.7 s (50-300 keV). The time-averaged spectrum from T0-4.1 s to T0+17.4 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.14 (+0.19/-0.17) and the cutoff energy, parameterized as Epeak, is 135.4 (+23.6/-23.0) keV. The event fluence (10-1000 keV) in this time interval is (2.0 +/- 0.2)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0-5.1 s in the 10-1000 keV band is 2.0 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
