The Rose City Astronomers club is working to establish relationships with other astronomy clubs around the world.

Sister club relationships are an important part of our club’s activities. They are established with active and organized astronomy clubs with whom RCA has a history of contact, exchange and/or personal relationships with members that motivates members of both clubs to commit to a moderate level of exchange necessary to continue and strengthen the arrangement.

We look forward to these relationships. We believe they will give our members opportunities to learn the night skies the world over and to meet other passionate amateur observers and develop lasting friendships. We expect these relationships to grow and mature over time, and as they do, our knowledge of Earth and Sky will continue to expand.
