GCN Circular 33517

Subject
GRB 230325A: Prompt enhanced Swift-XRT position
Date
2023-03-25T03:40:21Z (a year ago)
From
Phil Evans at U of Leicester <pae9@leicester.ac.uk>
P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:

Using  promptly downlinked XRT event data for GRB 230325A, we find an
enhanced XRT position of the afterglow: RA, Dec: 296.84935, -46.07561
which is equivalent to:
   RA (J2000)  = 19 47 23.85
   Dec (J2000) = -46 04 32.2
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/1161390.

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.
