That must have been where I heard about them. A friend tried to take a video of the bands with her cell phone, but you couldn't really see them.Those are called shadow bands or shadow snakes. I definitely saw them both before and after totality. They were covered in a video I linked to in the predictions thread. Pretty cool.
While I'm at it, the same guy also captured a transit of the ISS between C1 and C2. It seemed to catch a lot of attention on Twitter on Monday. He made a video of that event on his channel:
Very cool video, thanks for sharing!
