Named in honor of Clifton Darfield Ellyett (1915– ), pioneer of radar meteor research in New Zealand. After taking his Ph.D. at Jodrell Bank in the late 1940s, Ellyett returned to his native country and began a research program in radar meteors at what is now the University of Canterbury. In the early 1960s he carried out with Colin Keay {see planet  (5007)} the important southern-hemisphere radar patrol of meteors from near Christchurch. In 1965 Ellyett left to become professor of physics in the University of Newcastle (N.S.W.), starting there a new research group in atmospheric science. (M 29144) _ _.
