Partial solar eclipse, 29 Mar 2025
The Moon’s shadow misses the Earth’s centre, so nowhere sees more than a partial eclipse. Greatest eclipse was on Sat 29 Mar 2025 at 10:48 UTC. The next eclipse of the Sun is the annular solar eclipse of 6 Feb 2027.
Never look at the Sun without eclipse glasses.
- Greatest eclipse At 61.3°N 77.4°W, the Sun 0° up
- Magnitude 0.935 The share of the Sun’s diameter covered there
- Gamma 1.0418 The shadow’s axis from the Earth’s centre, in Earth radii

Latitude by latitude
Along each latitude, the longitudes that see any of the eclipse with the Sun up, and where on that latitude it is deepest: how much of the Sun’s face is hidden there, when, and how high the Sun stands.
| Latitude | Seen | Deepest (UTC) | Magnitude | At its deepest |
|---|---|---|---|---|
| 60°N | from 90°W to 95°E | 10:45 | 0.935 | Partial: at most 93% of the Sun hidden, at 76°W, the Sun 0° up |
| 45°N | from 80°W to 20°E | 10:19 | 0.860 | Partial: at most 83% of the Sun hidden, at 67°W, the Sun 0° up |
| 30°N | from 71°W to 4°E | 09:54 | 0.661 | Partial: at most 58% of the Sun hidden, at 60°W, the Sun 0° up |
| 15°N | from 63°W to 11°W | 09:34 | 0.351 | Partial: at most 24% of the Sun hidden, at 54°W, the Sun -1° up |
| 0° | Not seen | — | — | Not seen: the Moon’s shadow misses this latitude while the Sun is up |

How we worked it out: the Sun’s and the Moon’s places are Meeus’s solar and lunar theories, the ones the map draws. Greatest eclipse is the instant the shadow’s axis passes nearest the Earth’s centre, and the magnitude and the length of the total phase are measured from the place it meets the ground. Each latitude is walked 1° of longitude at a time on the Moon’s shadow cones, every 2 minutes, then refined where the eclipse is deepest with the Sun up. The tests hold these to NASA’s Five Millennium Canon of eclipses: instants within a few minutes, magnitudes within a few thousandths, the central duration within seconds.
