233472 Moorcroft           Discovered 2006 May 25 by P. A. Wiegert at Mauna Kea.
Donald Ross Moorcroft (b. 1935) is a Canadian physicist who did much to advance the field of radar backscatter from the auroral E-region ionosphere. He was the Chair of the Department of Physics of the University of Western Ontario from 1989 to 1998.
