GCN Circular 9988
R.L.C. Starling, P.A. Evans, A.P. Beardmore and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team: Using 4881 s of XRT Photon Counting mode data and 11 UVOT images for GRB 091003, 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 = 251.51980, 36.62470 which is equivalent to: RA (J2000): 16 46 4.75 Dec (J2000): +36 37 29.0 with an uncertainty of 1.7 arcsec (radius, 90% confidence). The UV counterpart reported in Gronwall & Starling (GCN Circ.9987) is consistent with this position. 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 circular is an official product of the Swift-XRT team.
