GCN Circular 23433
P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: Using promptly downlinked XRT event data for GRB 181123B, we find an enhanced XRT position of the afterglow: RA, Dec: 184.3670, 14.5979 which is equivalent to: RA (J2000) = 12 17 28.08 Dec (J2000) = +14 35 52.5 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/873186. Position enhancement is 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.
