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 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.
How can you tell the difference between granules on the sun and a sunspot?
you can't
Does halos form around the sun or moon mean an advancing rain or snow?
Halos around the sun or moon are typically caused by the refraction of light through ice crystals in the atmosphere, often indicating the presence of cirrus clouds. These clouds can signal that a warm front is approaching, which may bring rain or snow. Therefore, while halos do not guarantee precipitation, they can suggest that wet weather might be on the way.

What are ice halos?
When sunlight reflects and refracts off of tiny ice crystals in the atmosphere, the result can be ice crystal halos, which are related to rainbows. Ice crystal halos are most likely to occur in very cold, dry areas, such as Antartica. These conditions cause snow flakes to form very slowly, which tend to produce very clean hexagonal prisms. These prisms are very well suited to producing ice halos, and hence the ice halos are more normally produced in those areas.
How often do sundogs come into sight?
sun dogs come into sight when the sun is bored
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.

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.

Where did halos originate from?
Halos are optical phenomena that appear as bright circles around the sun or moon. They are caused by the refraction and reflection of light through ice crystals in the atmosphere.
Which cloud types are associated with halos?
Cirrostratus clouds are most commonly associated with halos. These thin, high clouds are made up of ice crystals that refract and reflect light, creating optical phenomena like halos around the sun or moon.
What causes halos around the sun and the moon?
Basic overview is that large explosions happen, because of the gas and density in the atmosphere. When the explosions cool down, and relax, they create halos. It occurs more on the sun, as the atmosphere is more dense and there is more gas.
What is a major significant difference between the sun and Jupiter?

Is there a difference between lemon sun in and the original?
The difference between SunIn and lemon SunIn is the addition of some form of lemon.
Why are sundogs called sundogs?
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.
