THE ROYAL ASTRONOMICAL SOCIETY OF CANADA STANDING COMMITTEE ON OBSERVATIONAL ACTIVITIES BULLETIN I MARCH, 1966 VARIABLE STAR SECTION Variable star observing is one of the most productive fields for the amateur, and undoubted- ly well organized fran an international standpoint. The American Association of Variable Star Observers (AAVSO) serves as the global clearing house for observations. With head- quarters located in Boston, Massachusetts, a full-time staff reduce, plot estimates and supply many institutions with light curves of approximately 1,000 variable stars. Virtually all amateur variable star observers belong to, or use the charts of, the AAVSO. We are fortunate that such a large and competent association has been developedo In view of this, it is not my intention to cc*nplicate matters by co-ordinating or soliciting observations from AAVSO observers located in Canada. Instead, I shall attempt co-ordination of the observers themselves. Exchanges of letters between variable star observers across Canada is nil. What size of telescopes are employed! Has photography an application to variable star observing? Do you need confirmation of the elusive minimum? And, most important - who is observing which stars and for how long? A list of members, their locations, and ounpieted observations follows: R.A.S.C. VARIABLE STAR OBSERVERS, 1961-1965 OBSERVER CENTRE NO. OF OBSERVATIONS *Hugh Ross Vancouver 2433 *Raymond Thompson Toronto 1903 *Francis Morgan Montreal 1259 Christopher Spratt Niagara Falls 999 Terry Dickinson Toronto 767 *G. L. Fortier Quebec D. A. Sherwood Unattached 537 *M. Lattey Unattached J. G. Craig Hamilton 265 John Baxter Toronto 209 N. Hutchings Unattached 108 David McAuslan Quebec 82 *D. J. FitzGerald Toronto 79 Leslie Sheldon Hamilton 62 R. Hawkins Montreal 54 Jim Low Montreal 45 10 other observers under 40 96 TOTAL FOR THE 5 YEARS 9894 *Denotes currently active observers. According to AAVSO records, Canada has more variable star observers than any other country outside the U.S.A. I will be sending a letter to each active observer in the R.A.S.C.; the frequency of these bulletins will depend largely on your response.
