Kennea (PSU) and P.A.\nEvans (U. Leicester) reports on behalf of the Swift-XRT team:\n\nSwift-XRT has conducted further observations of the field of the\nFermi/GBM-detected burst GRB 231129C. The observations now extend from\nT0+34.8 ks to T0+172.6 ks. The source previously reported, \"Source 2\",\nis believed to be the afterglow.  The position of this source is RA,\nDec=11.1769, -81.9936 which is equivalent to:\n\nRA (J2000): 00:44:42.45\nDec(J2000): -81:59:37.0\n\nwith an uncertainty of 9.5 arcsec (radius, 90% confidence).  This\nposition is 22.4 arcmin from the Fermi/GBM position.  We cannot\ndetermine at the present time whether the source is fading.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/00021633.\nThe results of the full analysis of the tiled XRT observations are\navailable at https://www.swift.ac.uk/xrt_products/TILED_GRB00117.\n\nThis circular is an official product of the Swift-XRT team.\n\n"
