THE EXPERIENCE
What it will actually be like
With 94.7% of the Sun covered the light noticeably weakens and cools, shadows grow sharp-edged, and the temperature drops. Gaps between leaves project rows of crescents onto the ground. The Sun remains dangerous to look at throughout.
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.
