The Rothney Astrophysical Observatory (RAO) is located near
Priddis, Alberta in the foothills of the Canadian Rockies. Located about
50km southwest of the University of Calgary campus, the RAO houses
several research grade instruments.
The RAO is operated by the Department of Physics & Astronomy of the University
of Calgary. T. A. Clark (Prof. Emeritus) &
E. F. Milone (Prof.)
had been Co-Directors since 1975. In October, 2003, Dr. Clark became Director
Emeritus, and Milone became sole director; Rene Plume assumed the role
of Associate Director, with special responsibility for outreach. In Sept. 2004,
Milone became Director Emeritus, and Plume, Acting Director. Plume also
chaired the Science Awareness and Promotion Visitor Centre upgrade committee.
Currently, Philip Langill is the director.
Built in 1972, the 16" Cassegrain was the first telescope to be used at the site. In the early 1980's work was initiated on the 1.80m A. R. (Sandy) Cross Telescope or ARCT (formerly the `Infrared Telescope' or IRT).

The ARCT is housed in a separate building, which also contains a Patrol Camera.

Now for something completely different. Here is a view of the crowded Open House on August 25, 2001 just before a talk on ancient astronomy (picture, courtesy of Steve Torchinsky):
The classroom, capable of accommodating 30 people, is clearly filled to overflowing for this event.
