Located in Portland, Oregon, the Rose City Astronomers (RCA) is the largest amateur astronomy club in the Pacific Northwest. As a non-profit volunteer organization, RCA is dedicated to promoting the enjoyment and education of astronomy to our members and the general public. A general membership meeting is held on the third Monday of each month at OMSI, usually featuring a noted guest speaking on an astronomy-related topic. Guests and potential members are welcome to attend any of our meetings.
