GCN Circular 23280
P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: Using promptly downlinked XRT event data for GRB 180930A, we find an enhanced XRT position of the afterglow: RA, Dec: 76.8633, -25.1169 which is equivalent to: RA (J2000) = 05 07 27.19 Dec (J2000) = -25 07 00.8 with an uncertainty of 2.0 arcseconds (radius, 90% confidence). Analysis of the promptly available data is online at http://www.swift.ac.uk/sper/864584. 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.
