TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4174 SUBJECT: GRB051028: Swift XRT Position DATE: 05/10/29 05:11:11 GMT FROM: Judith Racusin at PSU J. Racusin (PSU), K. Page (U. Leicester), J. Kennea, D. Morris, C. Pagani, D. Burrows (PSU), N. Gehrels (GSFC) on behalf of the Swift XRT team: The Swift XRT began observing the field of the HETE discovered GRB 051028 (Hurley et al., GCN 4172) at 20:44:08 UT, approximately 7.1 hours after the trigger. We have analyzed the first 3 orbits of data and we detect an uncatalogued fading X-ray source at the following coordinates: RA(J2000): 01 48 15.1 Dec(J2000): +47 45 12.5 with an estimated uncertainty of 6 arcseconds (90% containment), including corrections for the XRT boresight offset. This position is 5.2 arcminutes from the center of the HETE error box reported in Hurley et al. (GCN 4172). Note that the HETE error box quoted in Hurley et al. (GCN4172) actually extends beyond the field of view of the XRT. However, the source mentioned above is the only bright source in the field and is decaying. Therefore, it is likely the afterglow of GRB051028.
