TITLE: GCN CIRCULAR NUMBER: 8487 SUBJECT: Swift-XRT observations of GRB 081105 DATE: 08/11/06 15:41:23 GMT FROM: Andy Beardmore at U Leicester A.P. Beardmore (U. Leicester) and J. Cummings (GSFC/UMBC) report on behalf of the Swift-XRT team. The Swift-XRT started observing the field of the Swift-BAT and IPN localization GRB 081105 (Cummings et al., GCN 8484) at 2008-11-06 05:18:07(UT), 15.8 hours after the trigger. In an exposure of 5ks we detect an X-ray source within the BAT error circle at RA, Dec = 3.95224, 3.47098, which is RA (J2000) = 00:15:48.5 Dec (J2000) = +03:28:15.5 with an uncertainty of 4.8 arcsec (radius, 90 percent confidence). The observed count rate is (7.6+/-2.0)e-3 count/s. At this stage we cannot tell whether the source is fading. Further Swift observations are planned. This circular is an official product of the Swift-XRT team.
