7170 Livesey           Discovered 1987 June 30 by R. H. McNaught at Siding Spring.
Ron Livesey (b. 1929) has had a major influence on amateur astronomy, particularly in his native Scotland. He has been a key figure in organizing astronomical societies and observational programs, particularly of aurorae.
