P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
Using 1.4 ks of promptly downlinked XRT event data for GRB 251126A, we find an enhanced XRT position of the afterglow: RA, Dec: 99.94311, 54.98585 which is equivalent to: RA (J2000) = 06 39 46.35 Dec (J2000) = +54 59 09.1 with an uncertainty of 2.1 arcseconds (radius, 90% confidence). Analysis of the promptly available data is online at http://www.swift.ac.uk/sper/1417793.
Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).
