Burrows (PSU), J. D. Gropp\n(PSU) and P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT\nteam:\n\nSwift-XRT has performed follow-up observations of the\nSwift-BAT-detected burst GRB 231110A, collecting 10 ks of Photon\nCounting (PC) mode data between T0+8.9 ks and T0+61.1 ks. \n\nFour uncatalogued X-ray sources are detected consistent with being\nwithin 296 arcsec of the Swift-BAT position, of which one (\"Source 2\")\nis believed to be the afterglow.  The position of this source is RA,\nDec=356.2752, +82.6447 which is equivalent to:\n\nRA (J2000): 23:45:6.05\nDec(J2000): +82:38:40.9\n\nwith an uncertainty of 5.1 arcsec (radius, 90% confidence).  This\nposition is 85 arcsec from the Swift-BAT position.  There is evidence\nthat the source may be fading, however we cannot constrain the decay at\nthe current time\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/01195733.\nThe results of the full analysis of the XRT observations are available\nat https://www.swift.ac.uk/ToO_GRBs/01195733.\n\nThis circular is an official product of the Swift-XRT team.\n\n",
