Named in honor of Stanley William Milbourn {1925–1997}, editor of the circulars of the British Astronomical Association during 1969–1986, director of the comet section during 1968–1977 and currently assistant director of the computing section. Long interested in astronomical computations, particularly those involving returning periodic comets, he has produced a steady stream of accurate predictions over the years, as he has adapted procedures from mechanical calculating machine to pocket calculator to personal computer.
