There is a phenomenon in which we see in the sky a few Suns

If you have ever seen in the sky several suns, you have witnessed a curious natural phenomenon known as the "false sun" or sun dog: it can occur at any time of year, anywhere in the world, but it is not always clearly visible - the best Parghelia occur when the sun is low.

Pargely - is a special case of another optical phenomenon - the halo observed in the Sun, the Moon, and even the powerful streetlights: usually looks like a halo light ring around the light source, but may take the form of a cross, solar post or be like a rainbow. The cause of the halo - the refraction of light in ice crystals contained in cirrus clouds at a height of 5-10 km from the location of the crystals depends, will look like a halo.





One of the most common forms of halo - 22-degree Parghelia bright spots on either side of the Sun at its height at an angle of 22 from him. Ice crystals in the form of plates may promote the formation of secondary parhelion at the same height, but have an angle of 44 from the sun.



Another version - 120-degree Parghelia - pargelicheskom point on the circle, at an appropriate distance from the Sun: pargelichesky circle at the height of the light passes through the entire sky parallel to the horizon, it is usually white or rainbow colors.



There are also Parghelia Lilekvista arising when the crystal prisms are arranged horizontally in the clouds - a thickening pargelicheskogo range of 150-160 from the sun, and they called on behalf of the Swedish meteorologist for the first time to fix them.



Pargely sometimes confused with the false sunrise, when it has not yet risen, and his image has already appeared on the horizon, but this is another kind of halo - a sunny post (sometimes the same thing happens at sunset).



And the phenomenon known as antihelium ("Antisolntse") - the second sun, located on the opposite side of the horizon, and the phenomenon is similar to Parghelia observed the moon, called paraselene.
