Leicester) \nreport on behalf of the Swift-XRT team.\n\nUsing 639 s of XRT Photon Counting mode data and 1 UVOT\nimages for GRB 151111A, 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 = 56.84455, -44.16154 which is equivalent\nto:\n\nRA (J2000): 03h 47m 22.69s\nDec (J2000): -44d 09' 41.5\"\n\nwith an uncertainty of 1.8 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).\n\nThis circular was automatically generated, and is an official product of the\nSwift-XRT team.",
