How often have you seen green spots in the sky or flashes of green rays? This strange phenomenon, called a phenomenon from recent times, was observed by ancient people.
Their interest increased every time, because the ray appeared only for a moment, at sunset and at dawn. They began to study this second flash of green light, and it turned out that this happens as a result of the disappearance or appearance of the solar disk. Our atmosphere is amazing, and one of its amazing things is its ability to absorb and distort colors. Such a green reflection is a kind of large, natural optical illusion for the human eye, and this happens due to the absorption of yellow color, which is why we see a ray of exactly green color.
Where can you observe such a phenomenon, you ask? In order to see this phenomenon, you need to carefully prepare and choose the right time, as well as find a place with an open horizon, where the air is crystal clear, and there are not a single cloud in the sky. It is also worth taking the necessary equipment with you, such as binoculars or a telescope with a tube, because the green beam is difficult to see with the naked eye. Having caught the moment of sunrise or sunset, the green light will certainly sparkle, but you should not be zealous with observing the Sun. Using optics or simply observing bright light is easy enough to ruin your eyesight. As for the ray itself, this phenomenon can be seen in the early morning.
As a result of the refraction of light, accompanied by dispersion, the rays are decomposed into a spectrum, from which bright sunlight is later formed. At the beginning, for a few seconds, we see green light, then yellow, and only then red, it becomes the brightest, and then the Sun rises. Sometimes such a ray can acquire bluish tints, but this happens extremely rarely, and it lasts only from 20 to 30 seconds, and the green edge of the disk is hidden behind the horizon or becomes red. The green ray is most often seen at sea. Due to the sea water, the air becomes much cleaner, and on a summer evening there are no clouds in the sky. According to popular beliefs, whoever sees such a ray will expect infinite happiness.
