The parhelia also called sundogs and mock suns are
optical phenomena as one can see on either side of the
sun between 22° and 46°. Often they take place
at the same time as the halos.
More the Sun is high in altitude more parhelia are far
away from 22° halo.
You can see parhelia caused by reflection and scattering
of light from the moon witch they are called parselena
or "mock moons". But they are more difficult
and rare to see.
The color sequence is always that of the light spectrum
as the red of the rainbow is always oriented towards
the Sun and blue outward with sometimes followed by
a tail of white light. This white light can be so brilliant
sometimes, it looks like another sun.
They are among the optical phenomena caused by ice
crystals most common. To see the sun must be low enough.
In Europe, we can see about 73 per year. Their duration
of occurrence can be long.
