Leicester) reports on behalf of the Swift-XRT team:\n\nUsing 1.0 ks of promptly downlinked XRT event data for GRB 250615A, we\nfind an enhanced XRT position of the afterglow: RA, Dec: 290.38555,\n4.68527 which is equivalent to:\n   RA (J2000)  = 19 21 32.53\n   Dec (J2000) = +04 41 07.0\nwith an uncertainty of 2.0 arcseconds (radius, 90% confidence).\nAnalysis of the promptly available data is online at\nhttp://www.swift.ac.uk/sper/1324646.\n\nPosition enhancement is described by Goad et al.
