A partial solar eclipse will be visible to parts of the globe on March 29, 2025.

Partial solar eclipse

The partial solar eclipse of March 29, 2025, is visible from northeastern North America, Greenland, Iceland, the north Atlantic Ocean, most of Europe and northwestern Russia.

When and where to watch: The March 29, 2025, partial solar eclipse starts 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 – along its narrow path until 12:43 UTC.
Maximum eclipse: is at 10:47 UTC when 93% of the sun will be hidden behind the moon.

Moon, constellation, Saros

This partial solar eclipse occurs 0.8 days before the moon reaches perigee, its closest point to Earth.

During the eclipse, the sun is in front of the constellation Pisces.

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.

Viewers in the northeastern United States and southeastern Canada will see a partial solar eclipse as the sun is rising on March 29. The deepest part of the eclipse will happen before sunrise. But you’ll still see part of the sun covered for a while after sunrise. Start viewing as soon as the sun begins to appear above the horizon, when the moon will still cover an appreciable portion of the solar disk. Don’t forget to look for shadows on the ground mimicking the crescent shape of the eclipse in the sky. Use only safe solar filters when looking at a partially eclipsed sun!

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 2 (and possibly 3) eclipses to take place.

Then the second eclipse season will be 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, 2025.

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.

Bottom line: A deep partial solar eclipse will occur on Saturday, March 29, 2025. The path sweeps across northeastern North America, Greenland, Iceland, the north Atlantic Ocean, most of Europe and northwestern Russia.
