Anti-crepuscular rays can sometimes be viewed when looking opposite of the setting sun, as they appear when tall clouds in front of the rising or setting sun cast long shadows across the sky, which can be seen receding off into the distance when facing away from the Sun. This classic example was spotted over Scottsbluff, Nebraska, US.
