Ive seen two in the last decade. It’s surprisingly easy to know when it’s totality, and when it ends. Not only are there apps that do countdowns, but your eyes make it very clear if they’re disturbed by light or not.

Totality is incredible. A sight truly indescribable. A different color of white unimaginable, in a ring in the sky, animated like fire. I actually opened this comment section to come post this.
