Picture of the product

The Observer's Handbook, a 352-page guide published annually by The Royal Astronomical Society of Canada, has come to be regarded as the standard North American reference for data on the sky. The Handbook material is of interest to astronomers, scientists, teachers, students, science writers, campers, Scout and Guide leaders, and interested readers. The Handbook forms the basis of many secondary and university astronomy courses , and it should be in every library.

The various sections in the Observer's Handbook are of two kinds:


Upcoming Astronomical Events


Sections dealing with astronomical events occurring during the current year, including:


  • times of sunrise and sunset;
  • moonrise and moonset (for latitudes 20° to 60° N);
  • Moon phases and other lunar phenomenon;
  • conjunctions, elongations, etc. of the planets;
  • eclipses and transits;
  • location of the planets and 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.
