Star Almanack
Eclipses
The eclipse engine is now accurate enough to become part of the Almanack while validation and precision work continue separately.
What the Almanack will show
Each published eclipse entry can present the date, eclipse type, greatest-eclipse time in UTC, and concise observing or visibility information.
2026 eclipses
| Date | Eclipse | Greatest eclipse | Magnitude | Visibility | Observing note |
|---|---|---|---|---|---|
| February 17, 2026 | Annular solar | 12:14 UTC | 0.963 | Partial eclipse from southern Argentina and Chile, southern Africa, and Antarctica; annularity crosses Antarctica. | Use certified solar-eclipse viewers or a properly filtered telescope for the entire event; an annular eclipse never becomes safe to view directly. |
| March 3, 2026 | Total lunar | 11:31 UTC | 1.151 | Visible from eastern Asia, Australia, the Pacific, and the Americas wherever the Moon is above the horizon during the eclipse. | Safe to view directly. Binoculars or a small telescope can enhance the color and structure of Earth's shadow. |
| August 12, 2026 | Total solar | 17:48 UTC | 1.039 | Partial eclipse from northern North America, western Africa, and Europe; totality crosses the Arctic, Greenland, Iceland, and Spain. | Use certified solar-eclipse viewers or a properly filtered telescope during every partial phase. Direct viewing is safe only during the brief total phase for observers actually inside the path of totality. |
| August 28, 2026 | Partial lunar | 04:10 UTC | 0.930 | Visible from the eastern Pacific, the Americas, Europe, and Africa wherever the Moon is above the horizon during the eclipse. | Safe to view directly. Binoculars or a small telescope make the umbral boundary easier to follow across the lunar surface. |
Publication and research remain separate
The Almanack can publish useful eclipse predictions without declaring the underlying numerical work finished. Improvements to ephemerides, time scales, geometry, and validation can continue behind the published interface.

The 2026 eclipse list above is generated from the Star Almanack calculation data; validation and precision work continue separately.
