Still, little did we look at the sky, especially in winter, and in fact there can be seen a kind of halo, known as light (or solar) pillar - the beauty, reminiscent of the Northern Lights!
This visual atmospheric phenomenon occurs when reflection of artificial or natural light falling on the verge of ice crystals in the air. The light source in close to the surface or on the surface of the Earth, causes the appearance of a light pole over soaring crystals.
Light towers look like a narrow vertical columns that rise high up or sinking down from the light source (especially if this optical effect occurs at night and is caused by exposure to artificial light).
appearance of solar poles is under the influence of light from the sun or the moon. Glowing pillar seen by refraction of light through the crystals, however, depending on the angle, the light pole can be seen both above and below the light source.
Most light towers can be seen in the cold season, when ice crystals in low temperatures are formed in the lower atmosphere.
