TITLE: GCN CIRCULAR NUMBER: 11671 SUBJECT: GRB 110207A: Fermi GBM observation DATE: 11/02/08 16:02:07 GMT FROM: Andreas von Kienlin at MPE A. von Kienlin (MPE) reports on behalf of the Fermi GBM Team: "At 11:17:20.29 UT on 07 February 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110207A (trigger 318770242/ 110207470), which was also detected by the Swift/BAT (Littlejohns et al. 2011, GCN 11658) The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 72.8 degrees. The GBM light curve shows a multi-peaked structure with a duration (T90) of about 39 s (50-300 keV). The time-averaged spectrum from T0-0.256 s to T0+38.912 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.09 (+0.13/-0.12) and the cutoff energy, parameterized as Epeak, is 450 (+290/-130) keV. The event fluence (10-1000 keV) in this time interval is (4.4 +/- 0.6)E-06 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0+0.211 s in the 10-1000 keV band is 2.3 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
