If you see some sun in the sky, # 8230;
Sun dog is a special case of the halo optical phenomenon that can be observed is not one of the sun, but the moon and ... even the strongest street lights.
Externally halo - illuminated ring around the light source, but its shape may be different. Sometimes it takes the form of pillars, cross, and sometimes a rainbow. It arises because of the refraction of light in ice crystals at an altitude of 5-10 km, it depends on the location of the crystals will look like sun dog.
Most can be seen 22-degree parhelion: on both sides of the sun bright spots appear on the same height as the sun, the angle of 22 degrees from it. In addition to this type of Parghelia there are other varieties: 44-degree sun dog, and 120-degree. Pargely 120 degrees can be seen as a circle at the height of the sun, which passes through the sky parallel to the horizon, often white, sometimes rainbow colors.
In addition to these species, you can see Parghelia Lilekvista, they got their name by the name of a meteorologist from Sweden, for the first time to fix them. They arise when the crystal prisms are arranged horizontally in the clouds, and thickening pargelicheskogo range of 150-160 degrees from the sun.
In addition Parghelia can sometimes be seen as a phenomenon antihelium or antisolntse when there is a second sun, which is located on the opposite side from the present. The moon as it is possible to observe a phenomenon similar to mock sun, it is known as Parcel.
Mock moon occurs much less frequently Parghelia, even despite the fact that the conditions for the occurrence of the same phenomena.
Most often mock moon appears in the winter months, when the atmosphere is ice crystals. However, mock moon can occur at other times of the year when the match conditions favorable for the occurrence, namely, when high in the atmosphere, ice crystals form a hexagonal shape. The ice crystals refract the light of the moon, creating a drop-shaped or arc-shaped spots on either side of the moon. In addition, the moon during the emergence Parcel should be full or nearly full, and located not far above the horizon. Mock moon may have the same shape as the sun dog: circles, arcs.
Sometimes mock moon radiates brilliance, akin to the moon. Parselenu can be observed both in the south and in the northern hemisphere.
