In modern times, the lunar halo is an optical phenomenon caused by refraction, but in ancient times, the lunar halo had different meanings. So do you know the good or bad luck of the ancient lunar halo? What does it mean? Any omens? So let’s reveal it to you from the constellation knowledge below!
The good and bad luck of the lunar halo in ancient times: it was considered unlucky. The lunar halo is a natural phenomenon. It has the same principle as the rainbow. When the moonlight passes through the clouds at high altitude and is refracted by the ice crystals, the colorful light colors are dispersed into an inner ultraviolet and red halo, and form an aperture around the moon. This aperture is usually silvery white. The moon halo was called the "hairy moon" in ancient my country. People in ancient times believed that it would be unlucky to see a "hairy moon" on that night. Because people believed that this was the time when ghosts came out, the ancients generally would not go out on nights when there was a "hairy moon".
The lunar halo is when light passes through high-altitude cirrostratus clouds and is refracted by ice crystals, causing the seven-color composite light to be dispersed into a halo or arc of inner infrared and purple, creating a halo around the moon. Both the solar halo and the lunar halo are formed by refraction of ice crystals, which is the same as the rainbow. There is a folk proverb: "The sun is haloing and it rains at midnight, and the moon is haloing and it is windy at noon." The meteorological proverb "When the moon is haloed, it is windy; when it is moist, it is raining." This meteorological proverb refers to changes in the weather. The original meaning is that when the moonlight shines on the clouds and a halo appears, it will be windy; when the foundation stone is wet, it will rain. Halos can be divided into "small halo" and "large halo". "Small halo" is a 22-degree halo, and "big halo" is a 46-degree halo. A small halo is a circle with a luminous body as the center and an angular radius of 22 degrees. The inner ring is light red, and the outer ring is occasionally a purple or white halo. The sky inside the halo is obviously darker than outside the halo. The large halo is a halo with an angular radius of 46 degrees, which is very rare and is generally darker than the small halo. The moon halo was called the "hairy moon" in ancient times, and it was also called the "wind circle" in some places.
Appearance halos are usually ring-shaped or arc-shaped, and come in seven colors: red, orange, yellow, green, blue, indigo, and purple. Before the weather changed, we would sometimes see one or even two or more colored or white haloes around the moon, and the sunlight and moonlight seemed much dimmer.
