Extended Glow Preceding Reappearance of Saturn during a Lunar Occultation

Abstract

THE recent occultation of Saturn by the Moon1, visible across Canada in the early morning of Wednesday, October 17, 1973 provided the opportunity to observe and photograph the reappearance of the planet from behind the dark lunar limb. Teams of observers from the Calgary Centre of the Royal Astrononomical Society of Canada and the University of Calgary Physics Department established telescopes at various sites in Alberta but poor weather restricted photography of this event to times rather late in the reappearance and to a “close approach” sequence at the University of Calgary Rothney Astrophysical Observatory south of the shadow path.
