At greatest eclipse the Moon's disc spans 0.5571° against the Sun's 0.5256° — a ratio of 1.0600. Because the Moon appears larger, it covers the Sun completely and totality is possible.

Where you can see it

The shadow crosses the North Atlantic, North Africa and the Middle East, Europe, Africa, Central and South Asia and the Indian Ocean. Only along the central line does the Moon cover the Sun completely; a few hundred kilometres either side and it is a partial eclipse, which looks nothing like the same event.

Sorted by how much of the Sun disappears. Below about 40% nothing looks wrong to the naked eye — the Sun is so bright that losing a third of it changes very little. Never look without a proper solar filter regardless.

Greatest eclipse falls at 25.49°, 33.19° — the point where the axis passes closest to Earth's centre. The central line is computed from the Sun–Moon axis intersected with the geoid, and agrees with the reference coordinates to within a tenth of a kilometre.

Why eclipses come in seasons

The Moon's orbit is tilted about 5° to the ecliptic, so at most new and full moons it passes above or below the alignment. An eclipse needs the syzygy to coincide with the Moon being near one of the two nodes where the orbits cross. At this eclipse the Moon's ecliptic latitude was 0.144° — close enough to zero for the shadow to connect.
