Sister club relationships may be established with (1) any active and organized astronomy club (2) with whom RCA has a history of contact, exchange and/or personal relationships with members that (3) motivates members of both clubs to commit to a moderate level of exchange necessary to continue and strengthen the arrangement.

1. Each sister club relationship will be established by vote of the respective boards, and with a formal acknowledgement in the form of an exchange of certificates, signed and dated by each club’s president at the time. The certificate will be valid throughout the lifetime of the relationship, regardless of changes in officers.

2. The presidents of each club will automatically be a member of the other club.  RCA will pay the annual Astronomical League dues for the president(s) of our sister club(s).

3. Each club will select a liaison for the purpose of managing the relationship between the clubs.

4. The president or liaison of each club will exchange greetings and club information at least once every three months.

5. The president or liaison of each club may participate on the club forum site and/or on the email list.

6. Each club will maintain a prominent link to the other’s club on its website, if possible.

7. Each club will provide an introductory article for the other’s club that gives information about the club’s history, activities and members.

8. Members of sister clubs may submit articles for each other’s club communications.

9. Although English is the lingua franca of today, clubs may communicate in their own language(s).  It will be the responsibility of the sister club(s) to find and maintain contacts with people who can translate.

10. Sister club members will welcome each other, to the extent possible, when members travel to each other’s cities.   

11. If and when members of sister clubs come to Portland, they may check out books and telescopes from the RCA library, to the extent practicable. 

12. The clubs will actively search out joint astronomical projects.

13. The clubs may help each other in obtaining equipment and supplies that they may need.  

14. If one or the other club disbands or decides not to continue as a sister club, a simple letter to the current or last-known president will suffice to end the relationship.

      We look forward to establishing 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.
