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 member of the halo family, moon dogs are caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus clouds or cirrostratus clouds. They typically appear as a pair of faint patches of light, at around 22° to the left and right of the Moon, and at the same altitude above the horizon as the Moon.
The final full moon of meteorological winter illuminated the weekend sky, and for some skywatchers across the eastern United States, it created an eye-grabbing meteorological spectacle.
Lunar corona A solar corona up Beinn Mhòr (South Uist). In meteorology, a corona (plural coronae) is an optical phenomenon produced by the diffraction of sunlight or moonlight (or, occasionally, bright starlight or planetlight) [1] by individual small water droplets and sometimes tiny ice crystals of a cloud or on a foggy glass surface.
In the summer, the moon is closer to the celestial equator, as well as Earth's horizon due to the tilt of the planet's axis. This is why we see more vibrant-colored moons in the summer.
Glory around the shadow of a plane. The position of the glory's centre shows that the observer was in front of the wings. A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds.
The last full moon of 2024 will be the cold moon on December 15, according to the Farmers’ Almanac. The Leonids will be seen blazing in the night sky until the shower’s finality on December 2 ...
