Response to CaliforniaPeggy (Reply #9)

11. Dumb, dumb longship!

It's been too damned many decades since my astronomy classes. One forgets things and gets ones mix all talked up.

The umbra shadow is the one of totality. The penumbra is the partial eclipse shadow, so called the penultimate umbra.

Look for the umbra shadow crossing the ground just at the moment that totality begins. It's apparently very, very fast. Then, you'll have over two minutes of corona during totality.

I'm sure that there may very well may be some astronomers nearby. Enjoy it all.

As always, my best to you.
