Is that a sky with three Suns? Not really, it’s just a rare celestial illusion called parhelion’s, aka Sun Dog, an optical phenomenon that occurs with the refraction of light in the ice particles of the clouds.
Since Water can freeze in the atmosphere in small, flat, six-sided ice crystals, phenomena like this can show up unexpectedly.
As these crystals flutter towards the ground, they spend much of their time floating parallel to the ground.
“As these crystals flutter to the ground, much time is spent with their faces flat and parallel to the ground. An observer may find themselves in the same plane as many of the falling ice crystals near sunrise or sunset.”
Parhelions or Sun Dogs usually appear in the sky as a pair of subtly colored patches of light, approximately 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun.
During this strange alignment, each crystal can act as a miniature lens, reflecting the sunlight in our eyes and creating phenomena such as a Sun Dogs, explains NASA.
The video posted in this article was filmed and uploaded to YouTube by Hakan Hammar and was taken a month ago at the Vemdalen Ski Resort in central Sweden.
Visible in the center is the most direct image of the Sun, while two solar rays shine prominently from the left and right making it appear almost as if two more suns in the sky.
In the video we can clearly distinguish a bright halo of 22 degrees, as well as another rarer and much fainter halo of 46 degrees, also created by sunlight that is reflected in atmospheric ice crystals.
So, the next time someone tells you that they saw three sun’s in the sky, you’ll know that it’s not a conspiracy theory and that everything can be explained using science.
Similar phenomena can occur with the moon.
As explained by Time and Date, “Light from the Moon also creates glowing spots on both sides of the Moon, called moondogs. Also known as mock moon or paraselene, moondogs are rarer than sundogs because they only occur when the Moon is full or close to being full.”
