Osborne (U. Leicester)\nand P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the\nSwift/BAT-GUANO-detected burst GRB 220710A, collecting 4.4 ks of Photon\nCounting (PC) mode data between T0+242.5 ks and T0+287.4 ks. \n\nAn uncatalogued X-ray source is detected consistent with being within\n197 arcsec of the Swift/BAT-GUANO position and is above the 2SXPS\n3-sigma upper limit at this position, and is therefore likely the GRB\nafterglow.  The position of this source is RA, Dec=221.5668, +20.6576\nwhich is equivalent to:\n\nRA (J2000): 14:46:16.03\nDec(J2000): +20:39:27.3\n\nwith an uncertainty of 8.3 arcsec (radius, 90% confidence).  This\nposition is 83 arcsec from the Swift/BAT-GUANO position.  We cannot\ndetermine at the present time whether the source is fading.\n\nThe results of the XRT-team automatic analysis of the likely afterglow\nare at https://www.swift.ac.uk/ToO_GRBs/00021509/Source3.php.\nThe results of the full analysis of the XRT observations are available\nat https://www.swift.ac.uk/ToO_GRBs/00021509.\n\nThis circular is an official product of the Swift-XRT team.",
