Leicester) \nreport on behalf of the Swift-XRT team.\n\nUsing 2329 s of XRT Photon Counting mode data and 5 UVOT\nimages for GRB 090715B, we find an astrometrically corrected X-ray\nposition (using the XRT-UVOT alignment and matching UVOT field sources\nto the USNO-B1 catalogue): RA, Dec = 251.33969, +44.83889 which is equivalent\nto:\n\nRA (J2000): 16h 45m 21.53s\nDec (J2000): +44d 50' 20.0\"\n\nwith an uncertainty of 1.5 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, arXiv:0812.3662).\n\nThis circular was automatically generated, and is an official product of the\nSwift-XRT team.",
