69245 Persiceto           Discovered 1981 Mar. 1 by G. De Sanctis and H. Debehogne at the European Southern Observatory.
San Giovanni, in Persiceto, is a small town near Bologna, where an enthusiastic group of amateur astronomers, with the strong support of the municipality, created the Museo del Cielo e della Terra, a large complex devoted to the popularization of the natural sciences, in particular astronomy.
