15068 Wiegert           Discovered 1999 Jan. 13 by Spacewatch at Kitt Peak.
Paul Wiegert (b. 1967) studied at Simon Fraser University, University of Toronto, York University and Queen's University. He helped identify (3753) Cruithne as the first minor planet known to be co-orbital with the earth. The name was suggested by R. Jedicke and P. Jedicke.
