Protected eyes turned skyward Monday afternoon across South Carolina as the moon slowly covered the sun in the first coast-to-coast solar eclipse in 99 years. In Lancaster, where the eclipse wasn’t quite total, the slow dimming stopped at about 2:36 p.m. It was like dusk, with an odd yellowish tint. A crescendo of crickets and frogs rose and then fell off quickly as the light returned. Columbia, in the path of totality, drew huge crowds of astro-tourists.
