Encouraging Observation, Appreciation and Understanding
International Observe the Moon Night is a worldwide, public celebration of lunar science and exploration held annually since 2010. On October 16, 2021, your library is invited to join this world-wide celebration by hosting an event on one day each year to look at and learn about our Moon together.
International Observe the Moon Night is usually held in the fall, when the Moon is around first quarter. Fall in the Northern Hemisphere is generally a good time, 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.
