15462 Stumegan           Discovered 1999 Jan. 8 by Spacewatch at Kitt Peak.
Stewart A. Megan (b. 1952) discovered the Near Earth Object 2004 BV18 in conjunction with the Spacewatch Fast-Moving-Object Project. This find, made using real-time images transferred to volunteers over the Internet, encouraged others to join the online search.
