Stargazers across North America, South America, Africa, and Europe will experience a partial lunar eclipse on the night of August 27–28, 2026.
Timing and Visibility of the August 2026 Partial Lunar Eclipse
The celestial alignment will occur as Earth passes directly between the sun and moon during the full moon phase. Stargazers on the night side of Earth will catch their first glimpse of the planet’s umbra creeping onto the lunar surface at 10:33 p.m.
The shadow will continue across the cratered landscape until it reaches maximum eclipse at 12:12 a.m. EDT on August 28, or 0412 GMT. Observers watching from West Coast cities like California will witness the maximum phase shortly after midnight local time. Meanwhile, viewers in the United Kingdom will observe the peak shortly before sunrise on August 28 as the moon sits low on the southwestern horizon.
While the event spans multiple continents, local timings vary significantly depending on geographic location. The penumbral phase begins earlier in the evening at approximately 9:23 p.m. EST, marking the initial faint outline of Earth’s shadow touching the lunar disc.
Magnitude and Visual Appearance: Why the Moon May Turn Red
This event is classified as a partial eclipse rather than a total one. At its peak, it will cover a magnitude of 0.93 of the lunar surface, leaving a thin crescent still exposed to direct sunlight. While some reports cite an area coverage measurement of 96%, the umbral magnitude is 0.93.
Around the time of maximum eclipse, observers may notice the shadowed region of the moon take on a reddish-orange color. This visual phenomenon occurs because sunlight is filtered and bent through Earth’s atmosphere onto the lunar surface, creating the appearance often referred to as a “Blood Moon” during total eclipses.
Unlike solar eclipses, viewers do not need any special protective eyewear to watch a lunar eclipse safely. While naked-eye viewing is completely safe, a pair of quality binoculars or a telescope will give you a stunning view of Earth’s shadow racing across the lunar disk.
Public Viewing Events and Parkland Planetarium Plans
In Champaign, Illinois, the Parkland College planetarium is hosting a free telescope viewing of the lunar eclipse on Thursday, August 27, weather permitting.
Planetarium staff and members of the Champaign-Urbana Astronomical Society will position telescopes outside the building for visitors. The circle drive outside the planetarium and the Harold and Jean Miner Theatre will be blocked off to manage pedestrian traffic. Attendees can join the event from 9:30 p.m. to midnight, with parking available in the M1 lot.
The moon will start getting dimmer around 8:30 p.m. locally and move into Earth’s full shadow just after 9:30 p.m. Organizers note that the moon will remain over 90% covered just after 11 p.m. before staying partially eclipsed until nearly 1 a.m.
“I like taking any chance to look at the Moon, and lunar eclipses are a great way to see how Earth, the Moon, and the Sun interact with each other.”

Johnson added that it is amazing that people can use the shadow of Earth across the Moon to show that Earth is round and estimate the sizes and distances of these celestial bodies.
The Traditional Significance of August’s Sturgeon Moon
The late-August full moon coinciding with this eclipse is traditionally known as the Sturgeon Moon, named after the large fish found in several regions of North America, particularly around the Great Lakes.
Historical records trace the term to North American explorer Jonathan Carver and his 1778 publication, Travels through the interior parts of North-America in the years 1766, 1767, and 1768.
Carver attributed the monthly moon names to an unspecified Indigenous tribe, which are now understood to be primarily Algonquin in origin. He documented that the moon earned its moniker because in this month they catch great numbers of that fish.
Different Indigenous and cultural traditions attribute various names to the August full moon. These include the Corn Moon, Harvest Moon, Plum Moon, Huckleberry Moon, Courting Time Moon, and the Moon When Young Ducks Begin To Fly. Celtic traditions refer to the period as the Grain Moon and the Dispute Moon, reflecting both the harvest season and the traditional resolution of community disputes ahead of leaner winter months.
