Description
Sun pillar and parhelion. A sun pillar is a halo phenomenon in which a vertical streak of light appears above and below the sun, believed to be caused by the reflection of sunlight by ice crystals with vertical axes. Parthelion, sun dog, is an atmospheric optical phenomenon appearing in the sky as luminous spots 22 on each side of the Sun and at the same elevation as the Sun. Usually, the edges closest to the Sun will appear reddish. Other colours are occasionally visible, but more often the outer portions of each spot appear whitish.
