Optics in the solar eclipse!

Just a very short note: I’m on the road, aiming to be in the path of totality of the solar eclipse hitting tomorrow.  One of the things I’m going to be looking at, in addition to the ghostly hidden sun, is the sky surrounding it. I recently wrote a blog post for American Scientist about some of the history of sky measurements during the eclipse: what could be measured, and how?

There’s a bit about light, a bit about sky glow, and a bit about polarization. Check it out!

I will hopefully have more to say and show about the eclipse after I’ve seen it…
