7392 Kowalski           Discovered 1984 Mar. 6 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in honor of Richard Kowalski (b. 1963) of Quail Hollow Observatory, near Tampa, Florida. Kowalski is engaged in follow-up and discovery work on minor planets and comets. In 1998 he founded and has energetically maintained the Minor Planet Mailing List, a web-based information service and chat group for amateur and professional observers. Kowalski has also been the main organizer of the 1999 Amateur-Professional Minor Planet Workshop at the Lowell Observatory. Citation written by the discoverer and P. G. Comba.
