ALMOST GONE! This legendary book is the one reference every astronomer must have. The Observer's Handbook is a 352-page guide published annually since 1907 by The Royal Astronomical Society of Canada. Through its long tradition and the expertise of more than 60 contributors, the Observer's Handbook has come to be regarded as the standard North American reference for data on the sky. The material in the Handbook is of interest to professional and amateur astronomers, scientists, teachers at all levels, students, science writers, campers, Scout and Guide leaders, as well as interested general readers. The Observer's Handbook is an integral part of many astronomy courses at the secondary and university levels, and it should be on the reference shelf of every library. The various sections include: times of sunrise and sunset; moonrise and moonset (for latitudes 20º to 60º N); Moon phases and other lunar phenomena; conjunctions, elongations, etc. of the planets; eclipses and transits; location of the planets, dwarf, and minor planets; returns of periodic comets; times of meteor showers; predictions of occultations by the Moon and by planetary bodies; the orbital positions of the brighter satellites of both Jupiter and Saturn; and predictions of the cycles of many variable stars. A 24-page section, "The Sky Month By Month," gives an extensive listing of events for each month of the year.
