A trip of optical phenomena, between a 22-degree halo, tangent arc, and parhelic circle. Moriah shared that the parhelic circle was fully visible, wrapping around the entire sky. This optical treat was spotted over Antelope Valley, California, US.
A potential section of a Parhelic Circle, along with a Sun Dog. The former tends to be a fleeting optical effect, rarely lasting for long. It is most frequently observed as one or more extensions running between the Sun and the spots of light known as parhelia, or sun dogs, that give the effect its name. These optical phenomena were spotted over Antelope Valley, California, US.

The ice crystals in Cirrus, Cirrostratus and aircraft contrails over Singen, Germany formed the optical effect known as a parhelic circle. This is the horizontal bright band of light level with the Sun appearing in the cloud regions.
