International Observe the Moon Night will take place on October 5, 2019.  Its website describes the event as follows:


International Observe the Moon Night is a worldwide celebration of lunar science and exploration held annually since 2010. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest neighbor.

The event occurs in September or October, when the Moon is around first quarter. A first quarter Moon is visible in the afternoon and evening, a convenient time for most hosts and participants. Furthermore, the best lunar observing is typically along the dusk/dawn terminator, where shadows are the longest, rather than at full Moon.

10 Years of International Observe the Moon Night!

10 years ago, NASA’s Lunar Reconnaissance Orbiter (LRO) and its sister mission Lunar Crater Observation and Sensing Satellite (LCROSS) entered lunar orbit. From the interest and enthusiasm at events celebrating the occasion, International Observe the Moon Night was born.

In ten years, this program has expanded across the globe – and above it, to the International Space Station. This year, we invite you to join lunar enthusiasts around the world in a celebration of past, present, and future lunar exploration. This year also marks the 50th anniversary of the Apollo 11 Moon landing. We are building on the legacy of Apollo, reshaping our understanding of the Moon with an international fleet of robotic explorers, and preparing to return humans to the Moon through NASA’s Artemis program. There is much to celebrate.
