Such an atmospheric phenomenon, according to scientists, is extremely rare. For his appearance is necessary coincidence of several circumstances. Weather should be clear, and the light should be low on the horizon. Light creates the illusion of a few ice crystals in cirrus clouds at a height of 5-10 km. . Photo 2.
Halo (translated from the ancient Greek - circle drive; also aura, halo, halo) - an optical phenomenon, light ring around the light source. Halo usually appears around the sun or moon, sometimes around other powerful light sources such as street lights. There are many types of the halo, and they are mainly caused by ice crystals in cirrus clouds at a height of 5 - 10 km in the upper troposphere.Halo type depends on the shape and arrangement of crystals. Reflection and refraction of light by ice crystals often decompose in the range that does look like a rainbow halo.

A number of optical atmospheric phenomena caused by the refraction of light on the fine crystals located high (above 6 km) thin layer pinnately - stratus (International Classification are clouds Cirro-stratus, Cs). The scheme of the phenomenon of "false sun" (in Greek - Parghelia) simple - the direct rays of light from the light (sun, moon) almost seamlessly passes right through the thin layer of clouds, and while the rays coming at some predetermined angle, reflected and refracted from the flat faces of suspended crystals, which creates the effect of the reflection image of the light itself apart from him (typical angles of 22 and 44 angular gralusa). In addition to this beautiful phenomenon of "false sun" in the same way there are around the world "crown", "halo" (circle - see the figure), "light towers" and "light crosses", and these phenomena can be with iridescent tints, that is other optical phenomenon at high crystal clouds "irrizatsiya clouds."

These optical phenomena of nature are well known to meteorologists, weather described in textbooks and teaching manuals for weather observer weather stations all over the world, they are recorded and sometimes (if unusual phenomena) as sketched and photographed. But earlier in the last century, when people did not know the physics of the formation of this optical phenomenon, it is usually caused by not only the astonishment and admiration, but also a religious horror and usually perceived as unknown "heavenly sign" usually does not herald "nothing good", especially caused panic kind of "cross light" in the sky! Even now, when these optical phenomena described in encyclopedias and geography textbooks and natural history, people, often seeing them continue to be amazed and even try to "explain" the effect of the occurrence of "supernatural forces", "ET" and "parallel" worlds, such strange "explanation "These known optical phenomena can be found in the descriptions and brochures UFO logs!

But still there is:
Clickable 3000 pxZodiacal light - a faint glow, observed shortly after sunset or before sunrise (immediately after or just before the start of astronomical twilight).
Here's another interesting phenomenon: Light poles . Let's remember what some interesting natural phenomenon: that's like Polar, it is the northern lights . Let me remind you more about phenomena such as Ice finger of death .
