GCN Circular 11046
Elisabetta Bissaldi (MPE) reports on behalf of the Fermi GBM Team: "At 05:45:35.68 UT on 2 August 2010, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 100802A (trigger 302420737 / 100802240), which was also detected by the Swift-BAT (Troja et al. 2010, GCN 11031). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 76 degrees. The GBM light curve consists of an initial peak followed by a softer tail with a duration (T90) of about 100 s (50-300 keV). The time-averaged spectrum from T0 to T0+40 s is adequately fit by a power law function with an exponential high energy cutoff. The power law index is -1.17 (+0.21/-0.25) and the cutoff energy, parameterized as Epeak, is 149 (+41/-96) keV (Castor C-STAT 669 for 479 d.o.f.). The event fluence (10-1000 keV) in this time interval is (2.24 +/- 0.28)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+62 s in the 10-1000 keV band is 3.2 +/- 0.6 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
