CVA Star Party at Eastman Lake SUNRISE/SUNSET for SATURDAYS 7: 6:59 AM / 4:43 PM 4: 7:04 AM / 4:44 PM 2: 7:08 AM / 4:47 PM 28: 7: AM / 4:5 PM

26 Central Valley Astronomers, Inc. The Astronomy Club of Central California CVA is a local group of astronomy enthusiasts drawn together by common goals and interests. Goals: Provide a place for those interested in astronomy to meet together to enjoy and share their hobby. Share the wonders of astronomy with the public. Be a local source of astronomy education and information for our schools, the public, and the media. Interests: To learn about astronomy and related topics. To enjoy the night sky with unaided eyes, binoculars, and telescopes; to image the wonders of the universe. To learn from others and to share what we know about astronomy with others. CVA Observing Sites What we do Meetings: Monthly meetings are held at Fresno State (usually) on the Saturday closest to the Full Moon (usually). Star Parties and Public Observing: Monthly star parties are held on the Saturday closest to the New Moon (usually), at Eastman Lake (usually) in Madera County and occasionally at nearby Hensley Lake or Millerton Lake. We hold several star parties each summer at Courtright Reservoir (primitive camping). One weekend each summer we conduct a public star party at Glacier Point in Yosemite National Park. During spring, summer, and fall we conduct sidewalk astronomy at Riverpark Shopping Center on the Saturdays closest to the first quarter moon. Newsletter: Our monthly publication, The Observer, contains articles that share the knowledge and experiences of club members. Everyone is welcome to contribute. Workshops: Learn and share basic and specialized skills related to astronomy through club workshops. CVA at Fresno State Reaching out to others Discovery Center: We participate in events at The Discovery Center as part of our outreach program for the children and families of Central California. Downing Planetarium (CSUF): We are members of the Founders Circle of Donors at the Downing Planetarium. Kingsburg Observatory: We help maintain the observatory at Kingsburg High School and participate in their public events. Local Schools: We do free astronomy programs for schools and non-profit organizations. Come Join Us We always welcome newcomers and visitors. You need no special knowledge or skill to become a member. There is no age limit, and you need not own a telescope. You just need a curious mind. Contacting CVA Check our website, for current contact and membership information and larger maps to CVA activities. CVA is a nonprofit organization.
