Pillars of light


These two images you provided are actually Sun Dogs.
These are frequents in the Arctic and Canadian's North when the weather is extremely cold. Impressive, aren't they?

However, I've never seen pillars of lights before. Or the Moon surrounded by a halo. Really interesting!

Wikipedia's info on Sun Dogs:
A sun dog (or sundog) or mock sun, also called a parhelion[1] (plural parhelia) in meteorology, is an atmospheric optical phenomenon that consists of a bright spot to one or both sides of the Sun. Two sun dogs often flank the Sun within a 22° halo.

The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun. They can be seen anywhere in the world during any season, but are not always obvious or bright. Sun dogs are best seen and most conspicuous when the Sun is near the horizon.

Formation and characteristics​

Sun dogs are commonly caused by the refraction and scattering of light from horizontally oriented[2] plate-shaped hexagonal ice crystals either suspended in high and cold cirrus or cirrostratus clouds, or drifting in freezing moist air at low levels as diamond dust.[3] The crystals act as prisms, bending the light rays passing through them with a minimum deflection of 22°. As the crystals gently float downwards with their large hexagonal faces almost horizontal, sunlight is refracted horizontally, and sun dogs are seen to the left and right of the Sun. Larger plates wobble more, and thus produce taller sun dogs.[4]

Sun dogs are red-colored at the side nearest the Sun; farther out the colors grade through oranges to blue. The colors overlap considerably and are muted, never pure or saturated.[5] 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 latter is often missed by viewers, since it is located more or less directly overhead. Another halo variety often seen together with sun dogs is the 22° halo, which forms a ring at roughly the same angular distance from the sun as the sun dogs, thus appearing to interconnect them. As the Sun rises higher, the rays passing through the plate crystals are increasingly skewed from the horizontal plane, causing their angle of deviation to increase and the sun dogs to move farther from the 22° halo, while staying at the same elevation.[8]

It is possible to predict the forms of sun dogs as would be seen on other planets and moons. Mars might have sun dogs formed by both water-ice and CO2-ice. On the gas giant planets—Jupiter, Saturn, Uranus, and Neptune—other crystals form clouds of ammonia, methane, and other substances that can produce halos with four or more sun dogs.[9] (The rest of the article on Wikipedia Sun dog - Wikipedia)
 
Pillars of light appeared in the Leningrad region.

Local residents witnessed two optical phenomena at once: a lunar halo and columns of light were observed in the sky.

I also saw the halo around the sun yesterday, it's not unusual anymore to see this, especially in winter. But for the pillars of light, this this stange, are you sure there wasn't a event planned this night? They all seem to be grouped in one place.

Yeah, this is what I thought myself, Sun Dogs. I was confused by the description and the fact that photos look like they were took at night due to the surreal ambience. But thinking of it, it's not possible as we clearly see a lot of objects.

If a photographer can explain the blue rendering of the photos I'm interested.

You mean a sky event like an eclipse or something like that? I don't know but it's an interesting question.

The scientific explanation of light pillars is:
Light pillars are a meteorological phenomenon belonging to the family of solar halos. They can be seen every winter in the polar regions, in Canada, in the north of the United States (Montana, Alaska, the Great Lakes region), but also in Russia and in eastern and northern Europe (Scandinavia, Poland, etc.). Pillars of light have also sometimes been seen in France, mainly in the Alps, although they are less impressive than in the north of Europe and America.

A particular type of ice crystal needed

Pillars of light occur when certain specific conditions are met in the lower layers of the atmosphere. In the polar regions, fine ice crystals float suspended in the air: they may be very fine snow, or simply very fine clouds, such as cirrus clouds. Their formation then requires the presence of a particular type of ice crystals floating close to the ground, and under calm weather conditions, with no wind: special hexagon-shaped crystals are needed, which form under freezing temperatures, more particularly between -8 and -25°C. The ideal temperature is -12 to -16°C. These hexagon-shaped crystals are very flat and reflect sunlight or moonlight: they act like little mirrors.

To see these pillars appear, you need another artificial light source: street lamps, illuminated buildings, car headlights. The pillars then take on the colour of their original source, hence the fact that they can have different colours. They generally form when the sun is very low, just before sunset, but also throughout the night. The higher the concentration of ice crystals in the atmosphere, the bigger and brighter the pillars of light. It is quite possible to predict the ideal weather conditions for the formation of ice pillars (temperature, low wind, humidity in the air), but much more difficult to predict the type of ice crystals (hexagon) needed for the phenomenon to form.

So:
1/ The halos saw at the same time is consistent with the witnessing of the light pillars
2/ It can be due to car headlights as the sources of light are behind houses, like the photographer needed to not be dazzled. But that mean it was night... contradicting my point at the top of this message.
