Come hang out with us every month and learn something new! SDAA programs feature a wide array of speakers who share their expertise on unique and intriguing astronomy-related topics. We hold most of our meetings virtually via Zoom on the third Wednesday of every month. The meetings start at 7PM and last about one hour. We meet in-person for the March and November meetings at the Mission Trails Regional Park Visitor Center. Programs start with a few key club announcements and include information tailored to our new club members. Our featured speaker follows as the main event. Try your luck at winning SDAA club stickers with the fun astronomy quiz that closes out every meeting. Attendees are encouraged to engage and ask questions after speaker presentations. If you miss a program, you can catch the recordings on the SDAA YouTube page.
Please register in advance for the Zoom meetings at the following link. After registering, you will receive a confirmation email containing information about joining the meeting.
