Piranomonte (INAF/OAR) report on behalf of a \nlarger collaboration:\n\nAfter the report of the position of the possible X-ray counterpart \n(Burrows, GCN 4644) of the Swift trigger 180151 (Retter et al., GCN \n4641), we inspected again our images taken at Asiago (Piranomonte et \nal., GCN 4643).\n\nInside the XRT error circle we find a single object at the coordinates \n(J2000):\n  alpha = 06:54:03.85;\n  delta = +71:48:38.4.\nThe error is estimated to be less than 0.5\".\n\nThe magnitude of this object is R ~ 20.4 after assuming R=18.1 for the \ncloseby USNO star U1575_02633321 located 15 arcsec N-W.\n\nWe have no possibility yet to assess variability. Further observations \nare in progress.\n\nThis message can be cited.",
