THE EXPERIENCE

What it will actually be like

Only 7.2% of the Sun is covered, so nothing about the daylight in Naha will change. Through a safe solar filter the Moon shows as a shallow notch on one edge of the disc.

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 ON17:14 → 18:31 · 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.
