TITLE: GCN CIRCULAR NUMBER: 43007 SUBJECT: GRB 251205A: Enhanced Swift-XRT position DATE: 25/12/06 03:12:58 GMT FROM: Phil Evans at U of Leicester pae9@star.le.ac.uk
A.P. Beardmore, P.A. Evans, M.R. Goad and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team.
Using 366 s of XRT Photon Counting mode data and 1 UVOT images for GRB 251205A, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 200.27190, +29.92894 which is equivalent to:
RA (J2000): 13h 21m 05.26s Dec (J2000): +29d 55' 44.2"
with an uncertainty of 2.4 arcsec (radius, 90% confidence).
This position may be improved as more data are received. The latest position can be viewed at https://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).
