117032 Davidlane           Discovered 2004 May 14 by T. Glinos, D. Levy and W. Levy at Jarnac.
David Lane (b. 1963) is the author of The Earth Centered Universe, a brilliantly easy-to-use planetarium and telescope-control program. With Paul Gray, Lane has discovered three supernovae---SN1995F, 2005B and 2005ea. He is scheduled to assume the presidency of the Royal Astronomical Society of Canada in June 2008.
