TITLE: GCN CIRCULAR NUMBER: 7776 SUBJECT: GRB 080524: Swift XRT and UVOT analysis DATE: 08/05/28 19:35:41 GMT FROM: Dirk Grupe at PSU/Swift-XRT Dirk Grupe (PSU), Paul Kuin (MSSL), Jay Cummings (GSFC), and Kim Page (U Leicester) report of behalf of the Swift team: Swift observed the field of GRB 080524 (Sato et al., GCN Circ. 7774) as a Target of Opportunity for 10 ks starting on 2008-05-25 at 16:43:45 UT, 36h 30m after the burst. The exposures in XRT and UVOT V were 8.9 and 9.7 ks, respectively. Within the 2.5' BAT error circle no new source was found. In XRT the 3sigma upper limit is in the 0.5-8.0 keV band is 1.1e-3 counts/s which converts to roughly 4.7e-14 ergs/s/cm2 in the 0.3-10.0 keV band assuming an absorbed power law model with Galactic NH (5.19e20 cm-2) and a canonical X-ray Photon index Gamma=2.0. The 3sigma upper limit in the UVOT V-Filter is 20.0 mag. No further Swift observations are planned for this GRB. This circular is an official product of the Swift team.
