27413 Ambruster           Discovered 2000 Mar. 11 by the Catalina Sky Survey.
Carol Ambruster (1943-2013) did pioneering research on magnetic activity and flares of cool stars. She led Chaco Canyon work providing evidence for an early Navajo sun-watching tradition. Carol was the epitome of a perspicuous observer, with consummate interests also in music, art and history, and the natural world.
