About InOMN

International Observe the Moon Night (InOMN) is a worldwide, public celebration of lunar science and exploration held annually since 2010. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with Earth’s nearest neighbor.

InOMN is usually held in the fall, when the Moon is around first quarter. Fall in the Northern Hemisphere is generally a good time for InOMN, because of school schedules and the weather, and a first quarter Moon is visible in the afternoon and evening, a convenient time for most hosts and participants. Furthermore, the best observing is typically along the dusk/dawn terminator, where shadows are the longest, not at full Moon.

Everyone on Earth is invited to join the celebration by hosting or attending an InOMN event or just going outside and taking a moment to appreciate our closest cosmic neighbor.
