International Observe the Moon Night

International Observe the Moon Night (IOtMN) is an annual public outreach event … “that encourages observation, appreciation, and understanding of the Moon and its connection to planetary science and exploration” (Wikipedia). International Observe the Moon Night is sponsored by NASA’s Lunar Reconnaissance Orbiter mission and the Solar System Exploration Division at NASA’s Goddard Space Flight Center, with many contributors.

IOtMN occurs annually in September or October, when the Moon is around 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. This year’s event is officially Saturday, September 14th, two days after first quarter.

Follow the first link above to visit the NASA IOtMN website with a rich selection of resources, viewing tips and detailed maps of the lunar surface highlighting the best targets for viewing. For a detailed map of the moon on that night, check out this interactive page. There is also a downloadable map set with specific easy to view surface features and locations of the six Apollo landing sites.

You can enjoy the magic if viewing the moon by yourself at home or in one of many events hosted by  organized groups. And the resources above are all usable every month for your own personal exploration of the Moon!
