March 29 partial solar eclipse

When to watch: Maximum eclipse is at 10:47 UTC on March 29. Then 93% of the sun will be hidden behind the moon. Note: this is a very deep partial eclipse. When you’ll see the eclipse begin and end in your sky depends on your precise location.
Where to watch: The partial solar eclipse of March 29, 2025, will be visible from northeastern North America, Greenland, Iceland, the north Atlantic Ocean, most of Europe and northwestern Russia. Most of the continental U.S. will still be in darkness when this eclipse takes place. It’ll be early in the morning by our clocks, on March 29. So most of the continental U.S. will NOT see this eclipse. But a few people will see it! For example, in New York City, a less deep partial eclipse will be visible at sunrise. But, from there the eclipse won’t be so deep. The moon will appear to cover only about 22% of the sun. Practice eye safety when watching.
Eclipse duration on March 29: The eclipse begins near the northern coast of South America at 8:50 UTC. The deepest part of the eclipse is at 10:47 UTC. The partial eclipse remains visible through the last location – far northern Siberia – until 12:43 UTC.

Moon, constellation, Saros

This partial solar eclipse occurs less than a day (0.8 days) before the moon reaches perigee, its closest point to Earth. So this is a supermoon eclipse.

This is not a total eclipse. So the sky will not darken enough for you to see stars. But if you could see stars, you would find that – during this eclipse – the sun is in front of the constellation Pisces the Fishes.

The eclipse belongs to Saros 149 in the Saros catalog of eclipses that describes their periodicity. It is number 21 of 71 eclipses in the series. All eclipses in this series occur at the moon’s ascending node. The moon moves southward with respect to the node with each succeeding eclipse in the series.

Upcoming eclipses and eclipse seasons

The current eclipse season has two eclipses. This partial solar eclipse was preceded by a total lunar eclipse on March 13-14. They are part of the first eclipse season of 2025. An eclipse season is an approximate 35-day period during which it’s inevitable for at least two (and possibly three) eclipses to take place.

The second eclipse season of 2025 will fall in September. There will be a total lunar eclipse on September 7, 2025, followed two weeks later by a partial solar eclipse on September 21.

Nothing like perfect timing with a bird flying through the frame during the eclipse.” Thanks, James! The March 29 eclipse will be a partial, but deep, eclipse, similar to the eclipse shown in this photo.
