Leicester) reports on behalf of the Swift-XRT team:\n\nUsing  promptly downlinked XRT event data for GRB 230618A, we find an\nenhanced XRT position of the afterglow: RA, Dec: 196.60310, 3.30343\nwhich is equivalent to:\n   RA (J2000)  = 13 06 24.74\n   Dec (J2000) = +03 18 12.3\nwith an uncertainty of 1.9 arcseconds (radius, 90% confidence).\nAnalysis of the promptly available data is online at\nhttp://www.swift.ac.uk/sper/1175438.\n\nPosition enhancement is is described by Goad et al. (2007, A&A, 476,\n1401) and Evans et al. (2009, MNRAS, 397, 1177).\n\nThis circular is an official product of the Swift-XRT team.\n\n",
