P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:

Using  promptly downlinked XRT event data for GRB 241030B, we find an
enhanced XRT position of the afterglow: RA, Dec: 50.79269, 34.44691
which is equivalent to:
   RA (J2000)  = 03 23 10.24
   Dec (J2000) = +34 26 48.9
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/1263840.

Position enhancement is is described by Goad et al. (2007, A&A, 476,
1401) and Evans et al. (2009, MNRAS, 397, 1177).
