Oct 19, 2023 · A sun dog is an optical atmospheric phenomenon that causes bright spots at an angle of 22 degrees on one or both sides of the sun. It is also called a mock sun or parhelion in meteorology. Sun dogs occur as a result of the refraction or scattering of light from flat hexagonal-shaped ice crystals that are suspended in clouds.
Jul 25, 2006 · A sundog is a concentrated patch of sunlight occasionally seen about 22° to the left or right of the Sun. Sundogs often form in pairs on either side of our daytime star when sunlight refracts through icy clouds containing hexagonal platecrystals aligned with their large, flat faces parallel to the ground.
Sun dogs can be seen anywhere, any time of year or day. Best bet for seeing one is in the northern hemisphere with the Sun low in the sky.
Dec 15, 2023 · The most common of these is called a halo, or more specifically, a 22-degree halo. This appears as a ring of (usually) milky-white light centered on the sun with a 22-degree radius—about twice...
Sundogs tend to be most visible when the Sun is close to the horizon. The part of a sundog closest to the Sun tends to be red in color, while the areas further away from the Sun generally appear blue or green. Light from the Moon also creates glowing spots on both sides of the Moon, called moondogs. Also known as mock moon or paraselene ...
Sun dog, atmospheric optical phenomenon appearing in the sky as luminous spots 22 degrees on each side of the Sun and at the same elevation as the Sun. Usually, the edges closest to the Sun will appear reddish. Other colors are occasionally visible, but more often the outer portions of each spot appear whitish.
Apr 19, 2022 · In meteorology, a sun dog or parhelion is a bright spot on one or both sides of the Sun. Sun dogs or parhelia are around around 22° directly to the left and right of the Sun, sometimes accompanied by a 22° halo around the Sun.
