GCN Circular 41304

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

Using 923 s of promptly downlinked XRT event data for GRB 250809A, we
find an enhanced XRT position of the afterglow: RA, Dec: 233.00043,
-53.29626 which is equivalent to:
   RA (J2000)  = 15 32 00.10
   Dec (J2000) = -53 17 46.5
with an uncertainty of 3.0 arcseconds (radius, 90% confidence).
Analysis of the promptly available data is online at
http://www.swift.ac.uk/sper/1340954.

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