A partial solar eclipse occurred at the Moon’s ascending node (new moon) of orbit on Saturday, March 29, 2025,{{cite web|title=March 29, 2025 Partial Solar Eclipse|url=https://www.timeanddate.com/eclipse/solar/2025-march-29|publisher=timeanddate|access-date=August 13, 2024}} with a magnitude of 0.9376. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurred in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

The partial eclipse was visible for parts of the northeastern United States, eastern Canada, Greenland, Europe, Northwest Africa, and northwestern Russia.

Solar eclipses of 2022–2025

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.

= Eclipse season =

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

The series started with a partial solar eclipse on August 21, 1664. It contains total eclipses from April 9, 2043 through October 2, 2331; hybrid eclipses from October 13, 2349, through November 3, 2385; and annular eclipses from November 15, 2403, through July 13, 2800. The series ends at member 71 as a partial eclipse on September 28, 2926. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of totality will be produced by member 31 at 4 minutes, 10 seconds on July 17, 2205, and the longest duration of annularity will be produced by member 62 at 5 minutes, 6 seconds on June 21, 2764. All eclipses in this series occur at the Moon’s ascending node of orbit.{{Cite web|url=https://eclipse.gsfc.nasa.gov/SEsaros/SEsaros149.html|title=NASA – Catalog of Solar Eclipses of Saros 149|website=eclipse.gsfc.nasa.gov}}
