TITLE: GCN CIRCULAR NUMBER: 43532 SUBJECT: GRB 260127A: Prompt enhanced Swift-XRT position DATE: 26/01/27 19:08:40 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 1.6 ks of promptly downlinked XRT event data for GRB 260127A, we find an enhanced XRT position of the afterglow: RA, Dec: 231.87962, 6.76262 which is equivalent to: RA (J2000) = 15h 27m 31.11s Dec (J2000) = 00h 27m 03.03s with an uncertainty of 1.9 arcseconds (radius, 90% confidence). Analysis of the promptly available data is online at http://www.swift.ac.uk/sper/1444088. 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.
