We have a fun day planned for you at Cronyn Observatory on Saturday, September 19th – International Observe the Moon Night! 🌕

This annual event takes place in September or October, when the Moon is around first quarter – a great phase for evening observing. A first quarter Moon offers excellent viewing opportunities along the terminator (the line between night and day), where shadows bring the Moon’s cratered landscape to life.

This special event runs all day with something for everyone – bring the family out in the afternoon or join us for a regular public night in the evening.

Afternoon (2:00 to 6:00 pm) – perfect for kids and families:
🔍 Moon Mythbusters – can you tell Moon facts from Moon myths?
🌑 Crater Making Activity – create your own craters with flour and chocolate powder
🪨 Moon Meteorites – get up close with real Moon rocks

We will also set up a solar telescope for the Sun, and we’ll be able to observe the Moon (after 4:00 pm) and Venus. The observatory will be open for tours as well.

Evening (7:00 to 11:00 pm) – The evening part will be kicked off by a presentation on the Moon by Peter Jedicke, followed by a tour of the observatory and telescopes out for night sky observing if skies are clear. 🔭

FREE admission, no registration required! Drop in for any part of the day.

Date: Saturday, September 19th, 2026
