Royal Astronomical Society of Canada

From Wikipedia, the free encyclopedia

The Royal Astronomical Society of Canada (RASC) is a national, non-profit, charitable organization devoted to the advancement of astronomy and allied sciences. At present, there are 28 local branches of the Society, called Centres, located in towns and cities across the country from St. John's to Victoria.

The RASC is the Canadian equivalent of the British Astronomical Association. It was founded informally in the 1800s, but received a royal charter in 1903 from King Edward VII. The society incorporated nationally in 1968, prior to which its incorporation was limited to Ontario. The headquarters is in Toronto.

There are over 4300 members from coast to coast to coast. The membership, composed primarily of amateurs, also includes numerous professional astronomers and astronomy educators. Many members are relatively new to astronomy as a hobby. Introducing members to astronomy and the social aspects of the hobby is a big part of the Society's activities.

Each of the 28 Centres of the Society conducts a variety of activities of interest to its members and to the public. At regular meetings, well-known professional and amateur astronomers give lectures on a variety of topics of current interest. In addition, there are study and special-interest groups. Most Centres publish their own newsletters and hold their own group-observing events. Some members take part in regular observations of variable stars, lunar occultations, sunspots, meteors, comets and other phenomena; others develop special skills in astrophotography.

Most Centres have public education programs, including special star nights during the summer months when thousands of people are given an opportunity to look through a telescope courtesy of an RASC volunteer.

The RASC also publishes a number of books and periodicals. These include the annual Observer's Handbook, now in its 99th edition (2007), which is found in observatory control rooms and astronomer's reference shelves worldwide. Also published is a six issue per year magazine called the Journal and an annual astronomical wall calendar featuring photos by members.

The current president is Scott Young (2006-2008). His term will expire at the 2008 Annual Meeting.
