AI Insight

A deep partial lunar eclipse will occur on August 27-28, with 96.2% of the Moon entering Earth's umbral shadow, causing most of the lunar surface to take on a reddish color while a thin sliver remains illuminated. This is the deepest partial lunar eclipse visible from Earth until December 31, 2028. The eclipse will be visible from North and South America, Europe, Africa, and parts of western Asia, with observers in the Americas having optimal viewing conditions.


This rare astronomical event provides an excellent opportunity for public engagement with astronomy and skywatching, as such deep partial eclipses occur infrequently. The event requires no special equipment to observe safely, making it accessible to anyone with clear skies in the viewing regions.

The countdown is on for the deep partial lunar eclipse of Aug. 27-28. Over the next week, we’ll be bringing you the latest eclipse news, viewing tips as well as live updates throughout eclipse night.

Although this isn’t quite a total lunar eclipse, it’s pretty close! At maximum eclipse, 96.2% of the moon will slip into Earth’s dark central shadow known as the umbra, according to Time and Date. Much of the moon may take on a rusty red hue, while a thin sliver remains brightly illuminated.

It’s the deepest partial lunar eclipse visible anywhere on Earth until Dec. 31, 2028, making it a must-see event worth staying up late — or setting an alarm early — for.

We’re officially one week away from one of the best skywatching events of the year!

On the evening of Aug. 27 (for North America), or the early hours of Aug. 28 (for western Europe), Earth’s shadow will creep across the full moon during a very deep partial lunar eclipse. At maximum eclipse, 96.2% of the moon will be immersed in Earth’s dark central shadow.

The eclipse will be visible, at least in some part, from North and South America, Europe, Africa and parts of western Asia, weather permitting. Observers in the Americas are well-positioned for the best views while skywatchers across Europe will need to look toward the western horizon before sunrise as the eclipse reaches its peak.
