Anti-crepuscular rays
Anticrepuscular rays and shadows near Ashland, Wisconsin.     Taken 11 minutes after sunset, the rays appear to converge on the antisolar point already 2º high but behind the trees. The dark horizontal band is the shadow cast by the Earth onto the atmosphere. The band rises as twilight advances. Peg Zenko ( Tangent Photos  ) took this image on 7th June 2003. "I was pretty excited over this one, enough to venture out into a swampy area at dusk. In Wisconsin that makes one a mosquito buffet."     Photo ©2003 Peg Zenko, shown with permission.
