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.
