When it happens
Greatest eclipse
Global reference time: August 12, 2026 at 17:45 UTC. Your local calendar date may differ.
The global eclipse time and catalog duration are not a timetable for your exact location. Consult local circumstances for your start, maximum and end.
What to expect
Visibility & observing notes
Partial eclipse across northern North America, western Africa, Europe, the Atlantic, Arctic, and part of the Pacific; totality crosses the Arctic, Greenland, Iceland, northern Russia, Spain, and a small part of Portugal
Catalog regions: north_america, africa, europe, atlantic, arctic, pacific. These are broad regions; check the source map for your exact location.
Solar viewing needs proper protection
Use a safe solar viewer for partial and annular phases. Ordinary sunglasses are unsafe. Eclipse glasses do not make it safe to look through unfiltered binoculars, a camera or a telescope.
A solar eclipse requires the Moon to pass between Earth and the Sun near new moon. The Moon’s orbit is tilted by about five degrees to Earth’s orbital plane, so most new moons pass above or below the alignment needed for an eclipse.
Opens . Each scene is an exact daily sample, without interpolation; it is separate from the catalog peak of 17:45 UTC.
How to read the scene: Moonlight does not simulate eclipse shadows, red eclipse color or a solar eclipse viewed from Earth. The noon UTC sample is phase context, not a recreation of greatest eclipse.

Eclipses: a field guide
01
Your location makes the difference
A solar eclipse is visible only within its viewing region, and the central path is narrower still. Lunar eclipses require the Moon to be above your horizon. A regional description does not guarantee visibility at your exact location.
02
Greatest eclipse is a global time
The time in the catalog marks greatest eclipse. Your local start, maximum and end may differ. Follow the source maps and local circumstances before choosing an observing site.
03
Protect your eyes for solar viewing
Use a safe solar viewer that meets ISO 12312-2 for partial and annular phases. Ordinary sunglasses are not suitable. Never look through unfiltered binoculars, a camera or a telescope while wearing eclipse glasses; optics require appropriate front-mounted solar filters.
04
Clouds still matter
An eclipse can be geometrically visible and hidden by weather. Check the forecast close to the event and keep plans flexible. Lunar eclipses can be observed without special eye protection.
