What is another word for Parhelic Ring?
Pronunciation: [pɑːhˈɛlɪk ɹˈɪŋ] (IPA) 
A parhelic ring is a unique atmospheric phenomenon that causes a circle of light to form around the sun. It is also referred to by other names such as a sun halo, 22-degree halo, and a solar halo. Other synonyms for this phenomenon include circumzenithal arc, circumhorizontal arc, and infralateral arc.
The circumzenithal arc is a rainbow-like arc that appears toward the zenith of the sky and is caused by the reflection, refraction, and dispersion of sunlight. The circumhorizontal arc is another colorful arc that forms parallel to the horizon, caused by the same principles as the circumzenithal arc. The infralateral arc is a rare and unique form of a parhelic ring that appears below the sun, creating an arc of light just above the horizon.
