If you didn’t know, you’d expect a 91% eclipse to almost look like a full eclipse. But the sun is so bright that it still looks like day at 91%. You might not even realize there is an eclipse unless you looked at it with glasses.

When I saw it two days ago, even at 99% everything still looked normal. It was only a tiny bit darker outside. You still needed to use glasses to see that an eclipse was happening.

When it hit 100% it was like lights being turned out in a room. In place of the sun was a giant black disk with a multicolored glow around it and a bright red spot (solar flare was happening at the time).
