A light pillar or ice pillar is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source. The effect is created by the reflection of light from tiny ice crystals that are suspended in the atmosphere or that comprise high-altitude clouds (e.g. cirrostratus or cirrus clouds). [1]
Light pillars can also form around the Moon, and around street lights or other bright lights. Pillars forming from ground-based light sources may appear much taller than those associated with the Sun or Moon. Since the observer is closer to the light source, crystal orientation matters less in the formation of these pillars.
Meteorologist Alex O'Brien explains the science behind how light pillars occur and why they have been appearing in the sky recently.
Also visible are parts of the 22° halo (the arcs passing through each sun dog), a sun pillar (the vertical line), and the parhelic circle (the horizontal line). A sun dog (or sundog ) or mock sun , also called a parhelion [ 1 ] (plural parhelia ) in atmospheric science , is an atmospheric optical phenomenon that consists of a bright spot to ...

Temperatures need to be 10 degrees or lower, experts say.
Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates. One common example is the rainbow , when light from the Sun is reflected and refracted by water droplets.
