A 22° halo around the Sun, observed over Bretton Woods, New Hampshire, USA on February 13, 2021 A 22° halo and circumscribed halo around the Moon, observed near Kitt Peak National Observatory From top to bottom: A circumzenithal arc, supralateral arc, Parry arc, upper tangent arc, and 22° halo
A parhelic circle is a type of 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. [2] If the halo occurs due to light from the Moon rather than the Sun, it is known as a ...

On Thursday, residents of Mexico City were treated to a dazzling spectacle when a halo formed around the sun above the Mexican capital. Haloes like this one appear around the sun or moon when ...
Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun ...
22° halo around the Sun 22° halo around the Moon. A 22° halo is an atmospheric optical phenomenon that consists of a halo with an apparent diameter of approximately 22° around the Sun or Moon. Around the Sun, it may also be called a sun halo. [1] Around the Moon, it is also known as a moon ring, storm ring, or winter halo.
The shape of an upper tangent arc varies with the elevation of the Sun; while the Sun is low (less than 29–32°) it appears as an arc over the observed Sun forming a sharp angle. As the Sun is seen to rise above the Earth's horizon, the curved wings of the arc lower towards the 22° halo while gradually becoming longer.
As the sun goes from 27° to 32°, the apex of the arc touches the circumzenithal arc centered on zenith (as does the 46° halo when the sun is located between 15° and 27°). In addition, the supralateral arc is always located above the parhelic circle (the arc located below it is the infralateral arc ), and is never perfectly circular.
