sun pillar

A halo in the form of a pillar of light extending above or below the sun and usually seen when the sun is low in the sky.

It is explained by reflection by the sides of columnar ice crystals falling with their long axes horizontal. The term light pillar is sometimes used when the source of light is artificial, such as street lamps.
