GCN Circular 8054
M.C. Stroh (PSU) reports on behalf of the Swift-XRT team: We have analyzed the first two orbits of Swift-XRT data obtained for GRB 080802 (Baumgartner et al., GCN Circ. 8051), totaling 81s of Windowed Timing and 2.4ks of Photon Counting data. The X-ray light-curve begins with a single flare that peaks to ~40 cts/ s near T+100 seconds. The rest of the light-curve can be fit by a single broken power-law with an initial decay index of 2.91 +/- 0.33, second decay index of -0.51 +/- 0.25 and a break near T+1000s. Since the second decay index indicates brightening, we cannot accurately predict counting rates at T+24 or T+48 hours. The spectrum from the Windowed Timing data can be fit with a power-law in excess of the Galactic value (2.75e21 cm-2, Kalberla et al. 2005), with a column density of 4.8 (+2.0/-1.7)e21 cm^-2 and a photon index of 1.40 (+0.24/-0.22). The observed (unabsorbed) 0.3-10 keV flux is 4.78e-10 (4.95e-10) ergs/cm^2/s. This is an official product of the Swift-XRT team.
