Light pillar

Light pillar

A light pillar is a visual phenomenon created by the reflection of light from ice crystals with near horizontal parallel planar surfaces. The light can come from the sun (usually at or low to the horizon) in which case the phenomenon is called a "sun pillar" or "solar pillar". It can also come from the moon or from terrestrial sources such as streetlights.
