Unless you're literally living under a rock, you know there was a total solar eclipse that passed over the US (and other areas) today. Here in Wisconsin, we got about 90% coverage of the sun. It was noticeably dimmer outside for a while. I hesitate to say it was darker. It's amazing how strong just 10% of the energy from the sun really is.
The partial eclipse started here around 1:00, but it took me until just before 1:30 to figure out a good way to see it.
