Introduction
Analogous to a sundog is also called "Holiday", is a special form of halo Analogous to a sundog is also called "Holiday", is a special form of halo . it by clouds of ice crystals in the refraction, belonging to the atmosphere of a normal optical refraction phenomenon it by clouds of ice crystals in the refraction, belonging to the atmosphere of a normal optical refraction phenomenon .
due to clouds in the sky, and clouds are composed of ice crystals, through occasional arrangement to form a special shape of the reflector, when sunlight irradiates on a reflector will be refracted with a grain of salt, since the formation of such natural wonders due to clouds in the sky, and clouds are composed of ice crystals, through occasional arrangement to form a special shape of the reflector, when sunlight irradiates on a reflector will be refracted with a grain of salt, since the formation of such natural wonders . in very cold, there's high - altitude cirrus clouds, the distribution of a large number of tiny hexagonal ice crystals in very cold, there's high - altitude cirrus clouds, the distribution of a large number of tiny hexagonal ice crystals .
when this many of the ice crystals in the vicinity of sunrise or sunset, they act like a prism, so that the sunlight refracted, are formed around the sun, "halos" when this many of the ice crystals in the vicinity of sunrise or sunset, they act like a prism, so that the sunlight refracted, are formed around the sun, "halos". ice crystals in the sinking, neatly lined up vertically, so that the sunlight refracted toward the left and right along the horizontal direction of about 22, from icicle out of three of the ray of light in the eyes of a viewer, in the middle of the journey to the sun's rays, from the middle position of the sun directly, and is the true sun; beside the two light rays, by sunlight refracting through hexagonal crystal is refracted by the ice crystals in the sinking, neatly lined up vertically, so that the sunlight refracted toward the left and right along the horizontal direction of about 22, from icicle out of three of the ray of light in the eyes of a viewer, in the middle of the journey to the sun's rays, from the middle position of the sun directly, and is the true sun; beside the two light rays, by sunlight refracting through hexagonal crystal is refracted by the .
so that, in the eyes of the people in the middle of the true sun as soon as the sun and the other two, they are actually virtual so that, in the eyes of the people in the middle of the true sun as soon as the sun and the other two, they are actually virtual . because of the sun in the sky are often irregular hexagonal array of icicles, they cannot reflect the sun more of wonders,Thus such an atmospheric optical phenomenon anthelion is extremely unusual because of the sun in the sky are often irregular hexagonal array of icicles, they cannot reflect the sun more of wonders,Thus such an atmospheric optical phenomenon anthelion is extremely unusual .
"sundogs" will typically occur two" sun ", but also can appear sometimes three or four "sundogs" will typically occur two" sun ", but also can appear sometimes three or four . 3 3.
Records
Regarding parhelia, China has also been documented, "Huainanzi" stated: "when Yao, and leaves are withered, Yao asked Hou Yi Shooting Ten Suns pitching its nine Regarding parhelia, China has also been documented, "Huainanzi" stated: "when Yao, and leaves are withered, Yao asked Hou Yi Shooting Ten Suns pitching its nine ."".
Principle
When the air of many ice crystals in the vicinity of sunrise or sunset, the icicle out of three of the ray of light in the eyes of a viewer, in the middle of the journey to the sun's rays, from the middle position of the sun directly, and is the true sun; beside the two light rays, by sunlight refracting through hexagonal crystal is refracted by the When the air of many ice crystals in the vicinity of sunrise or sunset, the icicle out of three of the ray of light in the eyes of a viewer, in the middle of the journey to the sun's rays, from the middle position of the sun directly, and is the true sun; beside the two light rays, by sunlight refracting through hexagonal crystal is refracted by the . so that, in the eyes of the people in the middle of the true sun as soon as the sun and the other two, they are actually a three - dimensional shape of the sun's so that, in the eyes of the people in the middle of the true sun as soon as the sun and the other two, they are actually a three - dimensional shape of the sun's .

Formation Conditions
"sundogs" phenomenon needs to meet very stringent conditions "sundogs" phenomenon needs to meet very stringent conditions . First have altostratus, a cloud will form ice crystals; and secondly the cloud is thinner, the better light transmittance, so that the sunlight refracted; again the sun and ice crystals, and the angle between the observer would be, just to see her off a bit First have altostratus, a cloud will form ice crystals; and secondly the cloud is thinner, the better light transmittance, so that the sunlight refracted; again the sun and ice crystals, and the angle between the observer would be, just to see her off a bit .
therefore," sundogs" this extremely rare atmospheric optical phenomenon therefore," sundogs" this extremely rare atmospheric optical phenomenon . 4 even in the same area, this also is not available for all to see, "sundogs" phenomena of short duration, for the observer and the sun, the angle between the ice crystals must be just, and we will see" two suns" 4 even in the same area, this also is not available for all to see, "sundogs" phenomena of short duration, for the observer and the sun, the angle between the ice crystals must be just, and we will see" two suns" .
"with The Anthelic Arc Distinction
anthelic arc is formed by refracting sunlight of atmospheric optical phenomena, it is because sunlight is irradiated at an angle to the surface of the ground distance of approximately 6,000 to 8,000 - meter - high cloud of minute ice crystals formed on the rear of the refraction, These ice - bending surface and fine particles of salt than the day light flat faces in contact with the ice crystals, light propagates in each of the crystals of bending, and include red, orange, yellow, green, blue, indigo, violet and the like unique to the optical spectrum of seven colours of the rainbow anthelic arc is formed by refracting sunlight of atmospheric optical phenomena, it is because sunlight is irradiated at an angle to the surface of the ground distance of approximately 6,000 to 8,000 - meter - high cloud of minute ice crystals formed on the rear of the refraction, These ice - bending surface and fine particles of salt than the day light flat faces in contact with the ice crystals, light propagates in each of the crystals of bending, and include red, orange, yellow, green, blue, indigo, violet and the like unique to the optical spectrum of seven colours of the rainbow . this normal atmospheric optical phenomenon, its just too cold of the polar regions are more common than rainbows,But in a more moderate climate of the area is only occasionally seen this normal atmospheric optical phenomenon, its just too cold of the polar regions are more common than rainbows,But in a more moderate climate of the area is only occasionally seen .
