Located in Portland, Oregon, Rose City Astronomers (RCA) is dedicated to promoting the enjoyment and education of astronomy to our members and the general public.

The Rose City Astronomers was formed in 1988…

…as an organization of amateur astronomers dedicated to the promotion, education and enjoyment of astronomy among its membership and the general public. To support that goal, the RCA sponsors a variety of activities for its membership and the general public that are geared to family participation and focused on low or no cost so that all can afford to participate. In all cases, members volunteer their time, their own personal equipment, and cover their own personal expenses to put on a variety of activities. We are a 501(C3) non-profit public benefit organization.

Monthly General Meetings

General membership meetings of the Rose City Astronomers are free and open to the general public. The meetings begin at 7:30 p.m. on the third Monday of every month at the Oregon Museum of Science and Industry (OMSI) located at 1945 SE Water Avenue, Portland, OR 97214.

RCA is proud to be a memberof these organizations.
