Kennea (PSU), A. Tohuvavohu (U.\nToronto), B. Sbarufatti (PSU) and P.A. Evans (U. Leicester) report on\nbehalf of the Swift-XRT team:\n\nSwift-XRT has conducted further observations of the field of the\nSwift-BAT-detected burst GRB 210618A (Bernardini et al. GCN Circ.\n30250). The observations now extend from T0+3.7 ks to T0+424.9 ks. \n\nOf the sources reported by Osborne et al. (GCN Circ. 30252), \"Source 2\"\nis believed to be the afterglow.  The position of this source is RA,\nDec=235.7698, +46.0691 which is equivalent to:\n\nRA (J2000): 15:43:04.75\nDec(J2000): +46:04:08.6\n\nwith an uncertainty of 9.3 arcsec (radius, 90% confidence).  This\nposition is 2.6 arcmin from the Swift-BAT position.  The results of the\nXRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/01056426.\nThe results of the full analysis of the XRT observations are available\nat https://www.swift.ac.uk/ToO_GRBs/01056426.\n\nThis circular is an official product of the Swift-XRT team.",
