  "body": "K.L. Page, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the\nSwift-XRT team:\n\nUsing 1707 s of XRT Photon Counting mode data and 3 UVOT images, we find\nan astrometrically corrected X-ray position (using the XRT-UVOT alignment\nand matching UVOT field sources to the USNO-B1 catalogue): RA, Dec =\n255.33924, 1.58872 which is equivalent to:\n\nRA (J2000):  17 01 21.42\nDec (J2000): +01 35 19.4\n\nwith an uncertainty of 2.2 arcsec (radius, 90% confidence).\n\nThis position may be improved as more data are received.  The latest\nposition can be viewed at https://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).\n\nThis circular is an official product of the Swift-XRT team.\n",
