GCN Circular 15959
P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team: Using 1977 s of XRT Photon Counting mode data and 4 UVOT images, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 209.30516, 0.64193 which is equivalent to: RA (J2000): 13 57 13.24 Dec (J2000): +00 38 31.0 with an uncertainty of 1.8 arcsec (radius, 90% confidence). This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This position is 0.5 arc sec from the optical counterpart reported by Xu et al (GCN Circ. 15947), thus we believe this is the X-ray afterglow. This circular is an official product of the Swift-XRT team.
