OF THE SUN COVERED
Almost all of the Sun went. The light weakened and cooled noticeably, shadows sharpened, and the temperature dropped — but it did not get dark, and the remaining sliver was still blinding.

THE EXPERIENCE

With 93.9% of the Sun covered the light noticeably weakened and cooled, shadows grew sharp-edged, and the temperature dropped. Gaps between leaves projected rows of crescents onto the ground. The Sun stayed dangerous to look at throughout.
