Viewers on the Edge of the Shadow may see Strange Phenomena
Sargent is not located on the center of the total eclipse path. Totality will only last for a little under one minute in our town. However, that doesn’t mean that Sargent isn’t in a prime viewing area. At Space.com, Joe Rao makes the case that sometimes people prefer to be closer to the edge of the eclipse path. This is because certain strange eclipse phenomena will last 10 times longer when you are only a few miles from the edge. One of these phenomenons is called shadow bands.
As the moon almost covers the sun, it causes small strips of light to be projected through the earth’s atmosphere and dance on the ground. These are called shadow bands, and it may almost look like little snakes moving around. A good way to be able to see these shadow bands more clearly is to spread a white sheet on the ground. As I said before, we should be able to see these shadow bands a lot longer than those in the center of the shadow.
