With the sun rising behind Aldo Brando, the photographer, these anti-crepuscular rays were spotted. Anti-crepuscular rays 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, as was the case here, near Bogota, Colombia.
