International Observe the Moon Night is a worldwide celebration of lunar science and exploration, celestial observation, and our cultural and personal connections to the Moon. One day each year, everyone on Earth is invited to observe, learn about, and celebrate the Moon together – you’re invited to come to the observatory and see the moon (and other stuff) through many of our telescopes.

This year the event occurs in October when the Moon is just before the first quarter – a great phase for evening observing. Furthermore, the best lunar observing is typically along the Moon’s terminator (the line between night and day) where shadows are the longest, rather than at the full Moon.

If the skies are clear, we’ll open the dome and use the observatory telescopes, to look at features on the 6-day-old, 39% illuminated waxing gibbous moon.

International Observe the Moon Night is a time to come together with fellow Moon enthusiasts and curious people worldwide. Everyone on Earth is invited to learn about lunar science and exploration, take part in celestial observations, and honor cultural and personal connections to the Moon. We encourage everyone to interpret “observe” broadly!
