TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3365 SUBJECT: GRB 050505: Swift XRT Position DATE: 05/05/06 02:53:21 GMT FROM: Jamie A. Kennea at PSU/Swift-XRT J. A. Kennea, D. N. Burrows (PSU), C. P. Hurkett, J. P. Osbourne (U. Leicester) and N. Gehrels (NASA/GSFC) report on behalf of the Swift XRT team: The Swift BAT instrument detected a GRB at 23:22:21 UT on 5th May 2005 (GCN Circ 3360). The observatory executed an automated slew to the BAT position and the XRT began taking data at 00:09:23 UT on 6th May 2005. The XRT was in Auto state but was not able to centroid on the afterglow due to low source brightness. From downlinked data we find a uncatalogued X-ray source located at: RA(J2000) = 9:27:03.2, Dec(J2000) = +30:16:21.5 We estimate an uncertainty of about 6 arcseconds radius (90% containment). This position is 124 arcseconds from the BAT position reported in GCN 3364.
