International Observe the Moon Night (InOMN) is an annual event that is dedicated to encouraging people to ‘look up’ and take notice of our nearest neighbor, the Moon. From looking at the Moon with a naked eye to using the most sensitive telescope, every year on the same day, people from around the world hold events and activities that celebrate our Moon. On this site, you can find information about an InOMN event near you or register your own event. We encourage everyone to join us in the celebration!
