Stroh (PSU) reports on behalf of the Swift-XRT team:\n\nWe have analyzed the first two orbits of Swift-XRT data obtained for  \nGRB 080802 (Baumgartner et al., GCN Circ. 8051), totaling 81s of  \nWindowed Timing and 2.4ks of Photon Counting data.\n\nThe X-ray light-curve begins with a single flare that peaks to ~40 cts/ \ns near T+100 seconds. The rest of the light-curve can be fit by a  \nsingle broken power-law with an initial decay index of 2.91 +/- 0.33,  \nsecond decay index of -0.51 +/- 0.25 and a break near T+1000s. Since  \nthe second decay index indicates brightening, we cannot accurately  \npredict counting rates at T+24 or T+48 hours.\n\nThe spectrum from the Windowed Timing data can be fit with a power-law  \nin excess of the Galactic value (2.75e21 cm-2, Kalberla et al. 2005),  \nwith a column density of 4.8 (+2.0/-1.7)e21 cm^-2 and a photon index  \nof 1.40 (+0.24/-0.22). The observed (unabsorbed) 0.3-10 keV flux is  \n4.78e-10 (4.95e-10) ergs/cm^2/s.\n\nThis is an official product of the Swift-XRT team.",
