Named for Ken S. Russell, an astronomer at the U.K. Schmidt Telescope Unit, Siding Spring Observatory. For more than a decade, Russell has been concerned with most aspects of the operation of the 1.2-m U.K. Schmidt, including observation, data analysis and computer programming. He has been involved with the so-called ESO/SERC Southern Sky Survey and was instrumental in securing a very fine series of photographic images of P/Halley during its recent apparition. Russell has discovered five comets — four of them periodic — since 1979, and he worked on the observational phase of the U.K. Schmidt-Caltech Asteroid Survey in 1981. Recently, he began a collaboration with the discoverer on a deep astrometric survey of minor planets, bringing to bear his expertise in image recognition to the problem of semiautomatic identification and measurement of minor-planet images.
