Jun 29, 2016 at 3:05 comment added anna v @senshin It is in the sense that it is not a point source.
Jun 28, 2016 at 20:20 comment added senshin "The finite size of the sun..." - if the sun had infinite extent (say, if it appeared to be an infinite plane), convex objects wouldn't have shadows to begin with, would they? (Or is this supposed to be the "nonzero" sense of "finite"?)
Jun 28, 2016 at 18:44 comment added Chris Mueller It would be more accurate to say that air scatters some of the light rather than reflects it. Some of that scattered light is scattered backwards. The same is true for the twilight effect mentioned by @jpmc26.
Jun 28, 2016 at 18:16 comment added David Hammen The sun was behind the questioner. Mountain shadows are anti-crepuscular rays anther than crepuscular rays.

Jun 27, 2016 at 22:37 comment added jpmc26 Also on the note of air reflecting light: that's what causes the twilight periods. The sun isn't actually visible because it's below the horizon, but the sky is lit up by its light in the upper atmosphere being reflected back down.
