So we have seen three different kinds of atmospheric phenomena in these pictures… Sundogs or parhelia which consists of a pair of bright spots on either side on the Sun. Circumzenithal arc which is an optical phenomenon similar in appearance to a reverse rainbow. And finally a circumhorizontal arc which in its full form appear like a large, brightly spectrum-coloured band running parallel to the horizon, located below the Sun or Moon.

All these sky phenomena are members of a large family of halos, created by light interacting with ice crystals or rain in the atmosphere.
