Halo....

• Halo....

It is a rare occasion,where a special kind of halo far away from the sun could be seen in this diagram.This is a very attractive rainbow with circular rings.Innermost is the red coloured ring.Outer limiting ring is violet.These rings are formed from the diffracting light through the clouds made up of ice crystals high up in the sky between 6 000-10 000 metres from the earth.There are instances where this kind of halo could be seen around the moon too.
