There was a LOT of hoopla in my neck of the woods over the solar eclipse where we experienced 80 percent coverage of the sun. So, how dark did it get? It was anti-climactic; most of the effects associated with a solar eclipse occur only during or just before and after totality. At 80 percent it got slightly overcast, but if you didn't know there was an eclipse going on I doubt you would have noticed. As you can see from the photo of my backyard at the height of the eclipse it wasn't very impressive.
