Among the best-known halos is the 22° halo, often just called "halo", which appears as a large ring around the Sun or Moon with a radius of about 22° (roughly the width of an outstretched hand at arm's length).
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.
A post on X claims that “strange experiments” are causing rings to be seen around the sun in a photograph of the Arizona sky. Verdict: False This is called a “solar halo.” This is a ...
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 ...
In its full form, the arc has the appearance of a large, brightly spectrum-coloured band (red being the topmost colour) running parallel to the horizon, located far below the Sun or Moon. The distance between the arc and the Sun or Moon is twice as far as the common 22-degree halo. Often, when the halo-forming cloud is small or patchy, only ...
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 ...
Such parhelic circles are caused by horizontally oriented plate ice crystals reflecting sun rays. In order for a full circle to appear sun rays must be reflected both internally and externally. [56] [57] The circle surrounding the Sun is a 22° halo, as the name implies located 22° from the Sun.
A halo (from Ancient Greek ἅλως, hálōs, 'threshing floor, disk'), [1] [2] also called a nimbus, aureole, glory or gloriole (Latin: gloriola, lit. 'little glory'), is a crown of light rays, circle or disk of light [3] that surrounds a person in works of art.
