Leicester) \nreport on behalf of the Swift-XRT team.\n\nUsing 882 s of XRT Photon Counting mode data and 2 UVOT\nimages for GRB 190829A, 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 = 44.54402, -8.95837 which is equivalent\nto:\n\nRA (J2000): 02h 58m 10.57s\nDec (J2000): -08d 57' 30.1\"\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.",
