12583 Buckjean           Discovered 1999 Sept. 11 by D. K. Chesney at High Point.
Named for the discoverer's father, a railroad conductor, and his mother, a registered nurse. Both worked long hours to bring up their children, Gary, Dennis, Karen and Linda in Clovis, New Mexico. A Christmas gift of binoculars from his parents ultimately led to this discovery.
