12443 Paulsydney           Discovered 1996 Mar. 15 by the AMOS team at Haleakala.
With the gracious support of his family, Paul Sydney, a physicist on the AMOS team, has dedicated many long hours to demonstrating that U.S. Air Force assets could be applied successfully to following up minor planets. In return, the Air Force has benefited significantly from collaboration with the astronomical community.
