Leicester)\nreport on behalf of the Swift-XRT team.\n\nUsing 1310 s of XRT Photon Counting mode data and 1 UVOT images, we find an \nastrometrically corrected X-ray position (using the XRT-UVOT alignment and \nmatching to the USNO-B1 catalogue): RA, Dec = 119.84706, -56.63788 which is \nequivalent to:\n\nRA (J2000): 07 59 23.29\nDec (J2000): -56 38 16.4\n\nwith an uncertainty of 2.1 arcsec (90% confidence).\n\nThis position may be improved as more data are received. The latest position\ncan be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is\ndescribed by Goad et al. (2007, A&A, 476, 1401\nhttp://www.swift.ac.uk/xrt_positions/Goad.pdf), the current algorithm is an\nextension of this method.\n\nThis circular is an official product of the Swift-XRT team.",
