What time is the partial lunar eclipse?
Planning to watch the deep partial lunar eclipse this week? You’ll want to make sure you’re looking up at the right time.
The eclipse begins at 9:23 p.m. EDT on Aug. 27 (0123 GMT on Aug. 28), when the moon enters Earth’s faint outer shadow, known as the penumbra. From then, the eclipse will deepen and become more visible over several hours as the moon passes into Earth’s darker umbral shadow, ultimately leaving 96.2% of the lunar surface covered at its peak.
For key timings and when exactly to look up, check out our guide on when the partial lunar eclipse will occur.
What will happen during each stage of the partial lunar eclipse?
A partial lunar eclipse has five distinct phases that occur simultaneously for everyone on the night side of Earth as our planet slips between the sun and its natural satellite during the full moon phase.
The eclipse begins as Earth’s outer penumbral shadow subtly darkens the moon, after which the inner umbral shadow reveals our planet’s curved silhouette as it advances across the lunar disk.

3 days to go! Here’s everything you need to know
The deep partial lunar eclipse is just a few days away, so now is the perfect time to start planning how you’re going to view the “almost blood moon”.
At maximum eclipse, 96.2% of the moon’s surface will be covered by Earth’s dark central shadow known as the umbra. While the moon won’t be completely eclipsed — so this isn’t technically a “blood moon” — much of the lunar surface is expected to take on a reddish-orange hue, with just a thin sliver remaining brightly illuminated.
Check out our complete guide to the Aug. 27-28 partial lunar eclipse to make sure you’re ready for the “almost blood moon”.
How to view a partial lunar eclipse
One of the wonderful things about a lunar eclipse is that it can be witnessed by everyone who happens to be on the night side of Earth as it occurs, weather permitting.
You don’t need any special equipment like eclipse glasses to enjoy the show. Simply step outside and look up to see Earth’s curved inner shadow crawl across the moon in a spectacular display of orbital mechanics.
Want a closer look? No problem! It’s completely safe to point a pair of binoculars or a telescope at the moon during a lunar eclipse. Doing so will give you a magnified view of the colossal craters and dark lunar seas that mark the moon’s near side as they fall within the umbral shadow.

Where will the Aug. 27-28 partial lunar eclipse be visible?
The good news is that unlike a solar eclipse, a lunar eclipse can be seen from anywhere the moon is above the horizon. That means millions of skywatchers worldwide will have a chance to witness at least part of the Aug. 27-28 eclipse, weather permitting.
The best views will be from North and South America, where the entire eclipse will be visible. Across Europe and Africa, the eclipse takes place before dawn on Aug. 28, with the moon setting during the latter stages of the event.

Why this partial lunar eclipse is one you won’t want to miss
When most people hear the words “partial lunar eclipse,” they might often assume it will be less impressive than a total eclipse, and not really worth the effort to try and see it. But the Aug. 27-28 eclipse is anything but ordinary.
At maximum eclipse, 96.2% of the moon will be immersed in Earth’s umbra, the darkest part of our planet’s shadow. That means only a thin sliver of the lunar surface will remain directly illuminated by the sun, while the rest of the moon will take on a deep reddish-orange hue.
If you miss this one, you’ll have to wait until Dec. 31, 2028 for another lunar eclipse that rivals it in spectacle. So whether you’re planning on staying up late in the US or setting your alarms early in Europe, this is one skywatching show that’s well worth making time for!
1 week to go until the deepest partial lunar eclipse until 2028
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.
