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!
International Observe the Moon Night occurs annually 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 enhance the Moon’s cratered landscape.
You can join International Observe the Moon Night from wherever you are. Attend or host a virtual or in-person event, or observe the Moon from home. Connect with fellow lunar enthusiasts around the world through our Facebook page, #ObserveTheMoon on your preferred social media platform, and the International Observe the Moon Night Flickr group.
Outdoors, at home, online, or wherever you may be, we’re glad to have you with us. However you choose to observe, please follow local guidelines on health and safety.
Goals of International Observe the Moon Night:
- Unite people across the globe in a celebration of lunar observation, science, and exploration.
