Astronomers-for-a-day gasped and cheered as the much-ballyhooed Great American Eclipse rolled across the nation. Millions more took a break from work to peer at the partial eclipse visible everywhere in the U.S. Weather posed few problems for sky gazers, although it rained in parts of Missouri and was cloudy in much of South Carolina as the partial eclipse grew closer to totality. The skies above Charleston, S.C., the last major city in the path of totality, opened up just enough for stellar views of the eclipse, even as a thunderstorm moved in from the north, providing wild bolts of lightning.
