In becoming a member of the Analemma Society you actively contribute to children and adult science education through astronomical programs for the public. To become a member of the Analemma Society, you may join or renew upon paying annual membership dues.

We encourage you to become an Analemma Society member and to help us as a not-for-profit 501(c)3 organization to provide science education through astronomy activities at Observatory Park, Turner Farm in cooperation with the Fairfax County Park Authority.  In October 2016 the new Roll-Top Observatory will be dedicated with multiple telescopes for Friday night public observing. The view through a telescope stimulates our imagination in a way nothing else can. In this age of satellites and outer space travel, our future depends upon an appreciation and understanding of our celestial neighbors. This unique opportunity is available at Observatory Park sponsored by the Analemma Society. Our efforts have led to a major donation towards equipping the observatories to re-open October 1st.

We are working with the Fairfax County Park Authority to set up an education program to include public awareness of keeping dark skies. Analemma Society will inaugurate a series of educational programs covering Lunar Observing, Meteors, the history and meaning of Cosmic Rays and the history and construction of Sundials. We continue to seek volunteers, including the Northern Virginia Astronomy Club (NOVAC)) as we prepare to operate the Roll Top Observatory.

This year we hope you will help us grow our dedicated membership. We will be happy to speak with anyone to explain our exciting work! In renewing membership and donating to the Analemma Society, you actively contribute to children and adult science education through an important astronomical venue.
