P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
Using promptly downlinked XRT event data for GRB 191031C, we find an
enhanced XRT position of the afterglow: RA, Dec: 115.8709, -62.3251
which is equivalent to:
RA (J2000) = 07 43 29.01
Dec (J2000) = -62 19 30.5
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/932595.
Position enhancement is is described by Goad et al. (2007, A&A, 476,
1401) and Evans et al. (2009, MNRAS, 397, 1177).
