74625 Tieproject           Discovered 1999 Sept. 10 by G. Masi and F. Mallia at Campo Catino.
The Telescopes In Education (TIE) project makes it possible for many students around the world remotely to use telescopes at Mt. Wilson and Las Campanas, Chile. This is an innovative way to introduce astronomy to young people, among whom it has already developed intense interest.
