Again a phenomena of multiple suns has appeared in Russian skies.

It's not something unique, it happened before and it looks really nice.

Well I guess this is an example of weather phenomena called "icebow"
some case of "sun halo", which appears on high altitudes
(artcic/subarctic) on both hemispheres.

"An icebow is phenomenon similar to a rainbow except that it is formed
by the refraction of sunlight through cloud suspended ice crystals as
opposed to raindrops or other liquid water suspended in the air.
Generally the appearance is as arc sections as opposed to a full circle.
Brighter sections usually occur above, below, and lateral to the center
(where the sun is visible). These bright areas are referred to as "sun
dogs," "parhelia" (plural), or mock suns because of their bright
appearance and possible confusion with the actual location of the sun.
Those icebows that are caused by very small ice crystals are one colour,
because diffraction blurs the colours together. A 22 degree icebow has
red on the inside and blue on the outside."
