Leicester) report on behalf of the Swift-XRT team:\n\nUsing 4385 s of XRT Photon Counting mode data and 5 UVOT \nimages, we find an astrometrically corrected X-ray position (using the\nXRT-UVOT alignment and matching UVOT field sources to the USNO-B1\ncatalogue): RA, Dec =\n214.24065, -11.12845 which is equivalent to:\n\nRA (J2000):  14 16 57.76\nDec (J2000): -11 07 42.4\n\nwith an uncertainty of 1.4 arcsec (radius, 90% confidence).\n\nThis position may be improved as more data are received.  The latest\nposition can be viewed at http://www.swift.ac.uk/xrt_positions. Position\nenhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans\net al. (2009, MNRAS, 397, 1177).",
