On August 21,2017, I experienced the total eclipse of the sun. I witnessed this extraordinary event in the Teton Mountains of Wyoming.

​

Eclipse “Afterglow” is in the minute or two just before and after the sun is totally blocked, you may notice thin stripes of dark and light shadows moving rapidly in waves. These rare shadow fluctuations are called shadow bands or snake bands. Scientists are not certain what cause these shadows, but some believe that they are produced by turbulence in Earth’s constantly churning atmosphere. This is the same phenomenon that causes stars to twinkle. The star that causes our shadows to “twinkle” would be our very own sun!
