Rainbow around the sun.

Halo simply put - it is a rainbow around the sun. Rainbow that creators are not water droplets (as usual rainbow) and the rainbow that is created by ice crystals. Watch the halo in the sky at any time of year, day and night, around the sun or moon, and even around the lights or lamps.





Halo refers to the atmospheric optical phenomena, as well as rainbows and the aurora borealis.



The nature of this phenomenon - the dispersion of light in ice crystals. Unlike water droplets (which differ only in size) ice crystals come in different shapes and can fly in the air in different ways: hover, rotate, slowly falling, etc.



Therefore, rainbow raspogagaetsya always in the same place in the sky (you need to be back to the sun to be seen), and halo are different species (about a hundred).



Most often the halo can be seen in the late fall and winter.
