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 40 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. Sections dealing with astronomical events that occur during the current year. Information includes: * times of sunrise and sunset * moonrise and moonset (for latitudes 20 to 60 degrees N) * Moon phases and other lunar phenomenon * conjunctions, elongations, etc. of the planets * eclipses and transits * location of the planets and bright asteroids * returns of periodic comets * times of meteor showers * predictions of occultations by the Moon and by asteroids * the orbital positions of the brighter satellites of both Jupiter and Saturn * predictions of the cycles of many variable stars. There is a 24-page section called "The Sky Month By Month," which gives an extensive listing of events for each month of the year. 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.
