5682 Beresford           Discovered 1990 Oct. 9 by R. H. McNaught at Siding Spring.
Named in honor of Anthony Charles Beresford (b. 1942), prominent Australian amateur astronomer. Amongst his wide ranging astronomical interests he is an active artificial satellite observer, having been part of Operation Moonwatch from 1960 to 1975. He plays an important role in the dissemination of astronomical information and discoveries in South Australia. Always knowledgable about current events, Tony Beresford has been of considerable help to the discoverer on many occasions. Name suggested and citation endorsed by D. I. Steel.
