Partial lunar eclipse — August 28, 2026

Coming up: every phase timed to the minute, the same instant worldwide, converted to your own clock — and whether the moon is up where you are.

Partial lunar eclipse

August 28, 2026 · greatest eclipse 04:13 UTC

Part of the moon enters the Earth's umbra, taking a visible dark bite out of the disc; the rest stays in the fainter penumbra.

Can you see it?

A lunar eclipse has no narrow path — everyone on the night side of the Earth sees the same thing at the same instant. At greatest eclipse the moon is directly overhead near 9°S, 62°W, so it is best placed over the Americas. Further from there, the moon sits lower; on the far side of the world it is below the horizon and the eclipse happens in daylight.

Worked out from the moon's altitude at your coordinates at greatest eclipse. Cloud is not included — nothing on this site knows the weather.

What to expect

The umbra covers about 92% of the moon's diameter at maximum, over a partial phase of 3 h 17 min. The bite out of the disc is obvious to the naked eye; the shadow's edge is soft, not sharp.

No equipment and no eye protection are needed. Unlike a solar eclipse, a lunar eclipse is completely safe to watch with bare eyes.
