65657 Hube           Discovered 1982 Aug. 16 by A. Lowe on plates taken at Siding Spring.
At the University of Alberta, Douglas P. Hube (b. 1941) has specialized in the study of short-period, massive, binary-star systems through spectroscopic and photometric observations. A tireless promoter of astronomy locally, he served as national president of the Royal Astronomical Society of Canada from 1994 to 1996.
