Light pillar – Sun pillar – Optical phenomenon in atmosphere
Light pillar is an optical phenomenon. That arises in very cold weather when there are ice crystals in the shape of tiles in the air. They are also visible in clearly illuminated parts of cities. They are typical of the clouds of the high floor, but in the big cold they form at earth. They reflect then light from strong sources such as lanterns or fireworks on new year’s eve. As a result of such a source of light, the observer can see high light. Most often you can see them just before sunrise, or soon after his west. Another name of the whole phenomenon is a solar pillar.
