43193 Secinaro           Discovered 2000 Jan. 1 by L. Tesi and A. Boattini at San Marcello Pistoiese.
Secinaro, in the province of L´Aquila, is the location of what is probably the first meteoric impact crater discovered in Italy, dating to the fourth or fifth century. The town's mayor has established a "National Golden Meteorite Prize" for amateur astronomers who have conducted research on the solar system's minor bodies.
