2. Parhelic circleA parhelic circle is a halo, an optical phenomenon appearing as a horizontal white line on the same altitude as the sun, or occasionally the Moon. If complete, it stretches all around the sky, but more commonly it only appears in sections. Even fractions of parhelic circles are less common than sun dogs and 22° halos.
