International Observe the Moon Night
October 21 @ 5:00 pm - 10:00 pm EDTFree
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 honour cultural and personal connections to the Moon.
International Observe the Moon Night occurs annually in September or October when the Moon is around the 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.
