Parhelic Circle

The video introduces sun dogs and parhelic circles, explaining that parhelic circles are harder to spot but equally fascinating. These circles form through the reflection of sunlight on ice crystals in cirrus clouds, creating a white ring around the horizon. The position of the sun affects the height and size of the parhelic circle. Although they blend with clouds and are not always visible, they can be observed under the right conditions.
