Moon Maps for International Observe the Moon Night

Each year, we provide custom maps of the Moon with information about lunar locations that will be especially well-positioned for viewing on International Observe the Moon Night. Each map includes sections dedicated to lunar landforms, lunar maria (seas of basalt), and human landing sites. Many of the best views will occur along the terminator (the line between the day and night side of the Moon).

Moon Maps for the next International Observe the Moon Night will be available closer to the event date (September 19, 2026).

2025 Moon Maps

These maps depict the Moon as it appeared from the northern or southern hemisphere on International Observe the Moon Night, October 4, 2025.

Lunar Maria (Seas)

On International Observe the Moon Night 2025, observers had the opportunity to identify 16 Maria on the near side of the Moon. Once thought to be seas of water, these are actually large, flat plains of solidified basaltic lava. They can be viewed in binoculars or even with the unaided eye.

Human Landing Sites

Between July 1969 and December 1972 a total of 12 astronauts landed on the surface of the Moon for six of the Apollo missions. Apollo missions 11, 12, 14, 15, 16, and 17 each landed in different locations on the lunar surface. These locations, each fascinating for their own particular reasons, sampled a wide range of lunar geology and terrain, from smooth mare plains to rugged ancient highlands. The regions of all six landing sites were visible on International Observe the Moon Night 2025.
