Sundogs, also known as parhelia, are formed when sunlight passes through ice crystals in the air.
These ice crystals can be either in cirrus clouds high up in the atmosphere, where it's really cold, or closer to ground level as diamond dust (ice crystals floating freely in the air).
As the light passes through the crystals, it is refracted to split up the colours, just like light through a prism. The collective glints of millions of ice crystals combine to produce a sundog - and a whole load of other fascinating phenomena, a subject known as atmospheric optics.

How often do sundogs come into sight?
sun dogs come into sight when the sun is bored
Where can you see rainbows when it isn't raining?
You can see sundogs which come from sunlight striking clouds made of ice crystals which form in winter and in summer way up in the atmosphere. When visible, sundogs are always seen horizontally just to the right or left of the sun.
In what season might you find a sundog?
Sundogs are caused by light passing through ice crystals in the air - these can be in clouds (either cirrus or contrails), or at ground level as so-called diamond dust. Depending on climate, they are often seen all year round, although all halo phenomena such as these are more common in colder climes.

What is the difference between sun halos and sundogs?
Sundogs are sun halos - there are loads of similar effects caused by the same processes, known collectively as atmospheric optics.The sun halos you have probably seen are like huge circular rainbows around the sun, or perhaps an arc directly overhead. The former is called a 22-degrees halo, and the latter a circumzenithal arc - but there are many more halos that can form.Check out www.atoptics.co.uk for a more comprehensive guide to these, along with great explanations and pictures from around the world.Sundogs, also known as parhelia, are just one of these effects, caused by light passing through ice crystals in clouds (or at ground level) and being refracted to split up the colours - just like light going through a prism. The collective glints of millions of crystals bending the sunlight combine to make all these fascinating and beautiful phenomena, which can be seen from anywhere in the world at least part of the year.
What is a sundog?
The scientific name is a "parhelion". It's when there are bright spots in rings (formed by ice crystals) around the Sun in the sky. It's not seen too often, but usually it's seen best just before sunset. Sometimes it's called a "mock Sun" and I think that gives a better idea of what the phenomenon looks like.
What is the circle of light around the moon or sun?
The circle of light around the moon or sun is called a halo. Halos are optical phenomena caused by the refraction, reflection, and dispersion of light through ice crystals in the atmosphere. Different types of halos can form, such as 22-degree halos, sundogs, and circumzenithal arcs.

What are the different types of dispersion halos?
The two main types of dispersion halos are circular halo, which forms a ring around the sun or moon, and the parhelia or sundogs, which are bright spots seen at a 22-degree halo around the sun. Other less common types include tangent arcs, upper tangent arcs, circumzenithal arcs, and supralateral arcs.
