Observability

Members of the public are invited to view the wonders of the universe through the telescopes of NOVAC volunteers at the Smithsonian's Udvar-Hazy Center in Chantilly, VA. You do not need to be a member of the club or own any astronomical equipment to attend. Telescopes will be provided by the Smithsonian and pre-approved members of the NOVAC. No other personal telescopes are permitted at the event. The event will take place on the bus parking lot of the museum. **Please park your vehicle at the south end of the main visitors lot and follow signs and red lights to the observing site. As a reminder, parking during the event is free.** Have a cosmic question? One of NOVAC's astronomers or museum staff will be happy to help you. As the sky gets dark, be prepared to enjoy the wonders of the night sky! Don't forget to dress warmly. Please check the weather forecast. For lighting, cover a flashlight in red cellophane (the darker the better). Bring along water to keep hydrated. Note: This outdoor event is weather-dependent and may be cancelled because of significant cloud cover or precipitation.
