Anticrepuscular rays, or antisolar rays, [1] are meteorological optical phenomena similar to crepuscular rays, but appear opposite the Sun in the sky. Anticrepuscular rays are essentially parallel , but appear to converge toward the antisolar point , the vanishing point , due to a visual illusion from linear perspective .
Anticrepuscular rays while parallel in reality are sometimes visible in the sky in the direction opposite the sun. They appear to converge again at the distant horizon. Atmospheric refraction
These anticrepuscular rays appear to converge at the antisolar point, as viewed from an aircraft above the clouded ocean.. In some cases, sunbeams may extend across the sky and appear to converge at the antisolar point, the point on the celestial sphere opposite of the Sun's direction.
An Oklahoma-based photographer captured a stunning phenomenon in nearby Kansas as the sun set over the Great Plains, and AccuWeather meteorologists are able to explain how this unusual sunset got ...

Occasionally, around sunset or sunrise, anticrepuscular rays appear to converge toward the antisolar point near the horizon. [4] However, this is an optical illusion caused by perspective; in reality, the "rays" (i.e. bands of shadow) run near-parallel to each other. [5]
Loosely, the term crepuscular rays is sometimes extended to the general phenomenon of rays of sunlight that appear to converge at a point in the sky, irrespective of time of day. [ 3 ] [ 4 ] A rare related phenomena are anticrepuscular rays which can appear at the same time (and coloration) as crepuscular rays but in the opposite direction of ...
