2026-01-27T19:08:40.916Z | rev 0 | event: GRB 260127A

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).
