Preger (ASDC) report on behalf of the\nSwift-XRT team:\n\nWe analysed the first 3 orbits of XRT data for GRB 080714 (Perri et al.,\nGCN Circ. 7978) taken from 88s after the trigger (T0) in Windowed Timing\n(WT)\nmode and then in Photon Counting (PC) mode from T0+233 s to T0+9874 s.\nThe UVOT-enhanced XRT position was given by Goad et al. (GCN Circ. 7980).\n\nThe X-ray light curve from T0+88s up to ~T0+300s shows an initial 40 seconds\nlong flat segment followed by an increasingly steepening decay. Starting\nfrom\nT0+300s (PC data) the light curve can be fit with a power law model with a\nbest fit slope of 1.0+/-0.1.\n\nThe WT data spectrum from T0+88s to T0+231s is well fitted by an absorbed\npower law model with photon index Gamma=1.14+/-0.05 and a total equivalent\nhydrogen column density of NH=(0.3+/-0.1)e22 cm**-2. The Galactic NH is\n5.44e21 cm**-2 (Kalberla et al. 2005). The 0.3-10 keV observed (unabsorbed)\nflux is (3.4+/-0.2)e-10 erg/cm**2/s ((3.9+/-0.2)e-10 erg/cm**2/s).\n\nIf the light-curve continues to decay with the same rate, the count rate\n24 hours after the trigger is estimated to be ~6e-3 counts/s, which\ncorresponds to an observed flux of ~5e-13 erg/cm**2/s.\n\nThis is an official product of the Swift-XRT team.",
