A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Sunday, July 18, 2027,{{cite web|title=July 18–19, 2027 Almost Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2027-july-18|publisher=timeanddate|access-date=19 November 2024}} with an umbral magnitude of −1.0662. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. Occurring only about 16 hours before apogee (on July 19, 2027, at 7:50 UTC), the Moon's apparent diameter will be smaller.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2027&n=136|publisher=timeanddate|access-date=19 November 2024}}

The Moon will barely clip the edge of the Earth's penumbral shadow, and the eclipse will be impossible to see in practice. The event is listed as a miss by some sources.{{Cite web|url=https://www.timeanddate.com/eclipse/lunar/2027-july-18|title = Almost Lunar Eclipse on July 18-19, 2027 – Where and when to See}}
