TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4073 SUBJECT: GRB 051008: Swift XRT position DATE: 05/10/08 22:13:24 GMT FROM: Matteo Perri at ISAC/ASDC M. Perri, M. Capalbi (ASDC), D.N. Burrows (PSU) report on behalf of the Swift XRT team: We have analysed the first 2 orbits of ground data from GRB 051008 (trigger #158855, Marshall et al., GCN 4069). We find a previously uncatalogued, fading X-ray source within the BAT error circle at the following coordinates: RA(J2000) = 13 31 29.3 Dec(J2000) = +42 05 59 We estimate an uncertainty of 8 arcseconds (90% containment). This position lies 35 arcseconds from the BAT position reported in GCN 4069.
