85512 Rieugnie           Discovered 1997 Oct. 29 by C. Buil at Ramonville Saint Agne.
Yvon (b. 1932), Marc (b. 1966) and Delphine (b. 1960) Rieugnie helped many French amateur astronomers build their own telescopes and mirrors. They also contribute in the Association des Utilisateurs de Détecteurs Electroniques and the Société Astronomique de France.
