Stunning Iridescent Clouds Captured In Rare Sighting on Siberian Peak

Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface. It is a type of photometeor.You might on occasion see a rainbow-like cloud. They're fairly rare, but people do spot them, and sometimes they're lucky enough to capture photos of them. They're caused by the presence of very tiny ice crystals or water droplets in the air, which cause light to be diffracted (spread out).
