Haloszögek

Haloszögek, also known as halo rings or halos, are optical phenomena that appear as circular or elliptical rings of light around the sun or moon. They are caused by the refraction, reflection, or dispersion of light by ice crystals present in high and cold cirrus or cirrostratus clouds. Halos can vary in size and appearance, with the most common type being the 22-degree halo, which forms a complete circle around the sun or moon at a radius of approximately 22 degrees. Other types of halos include the sun dogs, which are bright spots on either side of the sun, and the circumzenithal arc, which appears as a bright red arc above the sun. Halos are often associated with atmospheric conditions that indicate the presence of high-altitude ice crystals, such as cold temperatures and low humidity. They are a fascinating and relatively rare optical phenomenon that can be observed under specific atmospheric conditions.
