I was surprised by how much light was still visible given the sun is 97% blacked out during the totality portion of an annular eclipse. While I didn't expect night skies that accompany totality in a total eclipse, I guess I was expecting it to be a bit more noticeable beyond it looking like a strange sunset without the sun on the horizon. It was physically cooler though (a good thing because it was pretty hot standing in the sun before the eclipse started) and overall a neat thing to see.
