THE EXPERIENCE

What it will actually be like

A distinct bite is taken out of the Sun, reaching 77% 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.

FILTER ON10:39 → 13:16 · the entire eclipse

Sunglasses, smoked glass, exposed film and phone screens are not filters. If you can see anything else through it, it is not dark enough.
