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.
Light pillars can also form around the Moon, and around street lights or other bright lights. Pillars forming from ground-based light sources may appear much taller than those associated with the Sun or Moon. Since the observer is closer to the light source, crystal orientation matters less in the formation of these pillars.
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 ...
There’s an old saying that goes like this: “Ring around the moon, rain soon.” Sometimes snow is part of it, too. Here’s our mythbuster breakdown on whether the moon can predict the weather.
In its full form, a corona consists of several concentric, pastel-colored rings around the celestial object and a central bright area called an aureole. [ 2 ] [ 3 ] The aureole is often (especially in case of the Moon ) the only visible part of the corona and has the appearance of a bluish-white disk which fades to reddish-brown towards the edge.
The colors of the sun dog finally merge into the white of the parhelic circle (if the latter is visible). [6] The same plate-shaped ice crystals that cause sun dogs are also responsible for the colorful circumzenithal arc, meaning that these two types of halo tend to co-occur. [7]
The arc is located a considerable distance (approximately 46°) above the observed Sun and at most forms a quarter of a circle centered on the zenith. It has been called "a smile in the sky", its first impression being that of an upside-down rainbow. The CZA is one of the brightest and most colorful members of the halo family. Its colors ...
The findings are based off data from Artemis I, a 25-day journey around the moon and back in late 2022. The Orion capsule on that mission, which followed a trajectory similar to the one Artemis II ...
