In the sky of Kosovo, some citizens today saw the phenomenon of a solar halo. This is scientifically explained as an atmospheric optical phenomenon, when a bright circle around the Sun is seen in the sky. This occurs as a result of the interaction of light with ice crystals in the atmosphere.
How is this formed?
When the ice crystals in the clouds pass through them, sunlight is refracted or reflected at an angle of 22 degrees. This refraction or reflection of the rays creates a white or grayish circle that can resemble a rainbow, explains the scientific platform “Britannica”.
The phenomenon is not rare, but it is not seen in many cases, as it depends a lot on atmospheric conditions.
Ice crystals are found at high altitudes in the atmosphere, typically 5 to 10 kilometers above Earth.
They form in or above clouds due to low temperatures.
