TITLE: GCN CIRCULAR NUMBER: 42071 SUBJECT: GRB 251003A: Prompt enhanced Swift-XRT position DATE: 25/10/03 02:22:53 GMT FROM: Phil Evans at U of Leicester <pae9@star.le.ac.uk> P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: Using 263 s of promptly downlinked XRT event data for GRB 251003A, we find an enhanced XRT position of the afterglow: RA, Dec: 18.52838, 56.49082 which is equivalent to: RA (J2000) = 01 14 06.81 Dec (J2000) = +56 29 26.9 with an uncertainty of 2.3 arcseconds (radius, 90% confidence). Analysis of the promptly available data is online at http://www.swift.ac.uk/sper/1400964. 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.
