45580 Renéracine           Discovered 2000 Feb. 10 by D. Bergeron at Val-des-Bois.
René Racine (b. 1939) has served as director of the Mt. Mégantic Observatory (1976-1980, 1984-1997) and the Canada-France-Hawaii Telescope (1980-1984). His research interests cover globular clusters, galaxies, astronomical instruments and adaptive optics. Some of his projects have earned him international renown.
