TOTAL SOLAR ECLIPSEUlaanbaatar, MongoliaMonday 2 July 2057 · times in UTC+8
2m 40s
OF TOTAL DARKNESS
The Moon crosses the centre of the Sun but is too far away to cover it, so a complete ring of sunlight remains. It never goes dark and it is never safe to look without a filter.

03 · DIRECTION
Where do I look?
At maximum the Sun is only 11° above the horizon to the east, so you will want an open view in that direction.
The Sun's height and bearing at maximum, from Ulaanbaatar. The horizon is at 0°.
THE EXPERIENCE
What it will actually be like
At maximum the Moon sits wholly inside the Sun's disc and leaves a complete ring of sunlight. There is no corona and no darkness — the remaining ring is still far too bright to look at — but the light goes strange and flat, and shadows sharpen.
SAFETY
Looking at it without hurting yourself
Keep a certified solar filter on for every part of the eclipse except totality itself. During totality, and only then, it is safe to look with the naked eye — and the filter must go back on the instant the Sun reappears.
Sunglasses, smoked glass, exposed film and phone screens are not filters. If you can see anything else through it, it is not dark enough.
