TITLE: GCN CIRCULAR NUMBER: 35452 SUBJECT: GRB 240101A: Enhanced Swift-XRT position DATE: 24/01/02 04:21:50 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 885 s of XRT Photon Counting mode data and 2 UVOT images for GRB 240101A, 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 = 10.34841, +8.51582 which is equivalent to:
RA (J2000): 00h 41m 23.62s Dec (J2000): +08d 30' 57.0"
with an uncertainty of 2.2 arcsec (radius, 90% confidence).
This position may be improved as more data are received. The latest position can be viewed at http://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).
