K.L. Page, C. Pagani, P.A. Evans and M.R. Goad (U. Leicester) report on
behalf of the Swift-XRT team:

Using 715 s of XRT Photon Counting mode data and 1 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 =
281.85530, -11.19412 which is equivalent to:

RA (J2000):  18 47 25.27
Dec (J2000): -11 11 38.8

with an uncertainty of 4.9 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).
