When is International Observe the Moon Night?
International Observe the Moon Night occurs annually in September or October, when the Moon is around first quarter. The first quarter Moon is ideal for late afternoon and evening observing.
Upcoming dates for International Observe the Moon Night:
- October 5, 2019
- September 26, 2020
- October 16, 2021
If we are unable to host an event on International Observe the Moon Night, can we have our event on another day?
Though we encourage everyone to participate in International Observe the Moon Night on a specific date each year, we understand that this date may not work for everyone. You are welcome to host your event on a different day. The main objectives are for you and your audience to look at the Moon, learn about the Moon, and to celebrate lunar science, exploration, and the personal and cultural connections to our nearest celestial neighbor. We encourage you to host your event as close to the official date as possible, because we select dates that are close to a first quarter Moon, which is visible in the afternoon and evening, a convenient time for most hosts and participants.

How can we get a scientist speaker or local support for our event?
Places to look for in-person help:
- The Solar System Ambassadors is a program that works with motivated volunteers around the country to share the latest science and discoveries of NASA’s space exploration missions by inspiring their community at local events. (Check a database of local Solar System Ambassadors in your area)
- The NASA Museum Alliance is a group of informal educators that is designed to help you navigate, find, or even create what you need to teach audiences about STEAM topics. (Check a map of local NASA Museum Alliance members.)
- The Night Sky Network connects local astronomy clubs with those interested in hosting events to bring the wonders of the universe to the public.
- Astronomers Without Borders is a network of people interested in astronomy from all over the world.
For additional in-person help, we suggest reaching out to your local university astronomy departments or clubs. Typically, university clubs are enthusiastic about public engagement and able to talk about current and cutting edge science happening in their fields.
Can we get an astronaut for our event?
Do you have a map of the Moon?
Each year, we make maps of the Moon with sites that will be visible on International Observe the Moon Night. Here's the 2019 Moon map. Additional materials about the Moon can be found on our Event Materials page.
