International Observe the Moon Night (InOMN) is a worldwide, public celebration of lunar science and exploration held annually since 2010. Tens of thousands of people participate each year, from 98 countries and 49 U.S. states (and counting!). On October 5th, your library is invited to join this world-wide celebration by hosting an InOMN event on one day each year to look at and learn about our Moon together.
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.
