An Italian photographer spent two hours outdoors documenting the spectacular phenomenon • "I took hundreds of pictures until I caught this special photo," he recounts • How does this happen?
Here is the explanation
Look at the sky at the right moment:
Italian photographer Alberto Gizi (45), this week managed to photograph a spectacular phenomenon in which a colorful aura (ring) surrounds the moon - and conquered the web.
It is a spectacle that takes place every year because of very high light feather clouds, dust, steam and ice crystals that are in the atmosphere.
"I saw this phenomenon happen many times, but usually I did not have the appropriate photographic equipment to document. This week I was at home and went up to the roof from 10 o'clock at night until midnight. I took hundreds of pictures until I caught this special picture," said the photographer.
The photograph that Gizi managed to capture, includes the moon at a very detailed level including some of his craters, with a beautiful aura of colorful light around it along with twinkling stars in the background.
In addition, a number of transparent clouds can be seen floating in the Earth's atmosphere.
As mentioned, and as we explained before, the beautiful aura is created as a result of the refraction of light rays in ice crystals in feather clouds (cirrus) at an altitude of about 5000 meters.
The rays of light are refracted in these ice crystals at a constant angle of 22 degrees so it is also the diameter of the aura.
Because of this, by the way, it is also called "Aura 22".
Usually, however, the refraction of light in this frozen prism fails to highlight all shades of light, and only a distant white aura could be discerned.
In the present case, due to very thin clouds and with the help of tiny drops a beautiful and wide refraction of light was created.
A similar phenomenon occurs even when an arc appears.
