TITLE: GCN CIRCULAR NUMBER: 19033 SUBJECT: GRB160220B: Enhanced Swift-XRT position DATE: 16/02/20 19:20:32 GMT FROM: Kim Page at U.of Leicester P.A. Evans, M.R. Goad, J.P. Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team: Using 4686 s of XRT Photon Counting mode data and 8 UVOT images, 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 = 259.86518, -18.12401 which is equivalent to: RA (J2000): 17 19 27.64 Dec (J2000): -18 07 26.5 with an uncertainty of 1.5 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). This circular is an official product of the Swift-XRT team.
