293926 Harrystine           Discovered 2007 Oct. 2 at the Astronomical Research Observatory, Charleston.
G. Harry Stine (b. 1928) helped found the hobby of spacemodeling (model rocketry) in 1957, a pastime enjoyed today by millions of space and astronomy enthusiasts worldwide. He also founded the National Association of Rocketry (Model Missiles Association) in 1959. Name suggested by P. Miller.
