DATE:    25/11/26 19:53:46 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 1.4 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).
