03 · DIRECTION
Where do I look?
At maximum the Sun is only 33° above the horizon to the south-east, so you will want an open view in that direction.

THE EXPERIENCE
What it will actually be like
A distinct bite is taken out of the Sun, reaching 48.6% at maximum. Daylight barely changes — the eye adapts far too well for that — so this is an eclipse you have to know about to notice. Use a filter; the remaining Sun is as dangerous as an uneclipsed one.
SAFETY
Looking at it without hurting yourself
A certified solar filter stays on for the whole eclipse. The Sun is never completely covered here, and what remains is as dangerous to look at as an uneclipsed Sun. Sunglasses are not a filter.
Sunglasses, smoked glass, exposed film and phone screens are not filters. If you can see anything else through it, it is not dark enough.
04 · POSITION
Should I travel?
This eclipse is partial everywhere on Earth — the Moon's dark shadow passes above or below the planet entirely, so there is no path of totality to travel to, from Ulaanbaatar or anywhere else.
