On the 24th of January 2020. Some really rare clouds were spotted in Oslo (Norway) that I have never seen before. The clouds were fluffy with lots of colors showing on the sides of them. The colors were spanning from white green to violet red color. It is something that I have only seen once in my lifetime and I had to take photos of them on my way to Ryen Metro station.
Here are some of the phots of the Polar stratospheric Clouds

Very rare clouds seen in Oslo for sure
After doing some researches. I found out that these clouds are very rare. So, I think it was nice to take some shots and document them. At this science education site, it seems like they are Lenticular Clouds but I finally got to know that they are Polar stratospheric clouds. Please correct me. But in the description of Lenticular Cloud, they fit into description. It seems like they are the polar versions of them for me:
Lenticular, or lee wave, clouds form downwind of an obstacle in the path of a strong air current. In the Boulder, Colorado area, the obstacle is the Front Range of the Rocky Mountains, seen at the bottom of the picture. Wind blows most types of clouds across the sky, but lenticular clouds seem to stay in one place. Air moves up and over a mountain, with the lenticular cloud forming just past the mountaintop. The cloud evaporates on the downwind side, so it appears stationary even though air is moving through the cloud. Lenticular clouds are lens-shaped and often look like flying saucers.
FACTS about Polar stratospheric clouds
These type clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m. They are best observed during civil twilight, when the Sun is between 1 and 6 degrees below the horizon, as well as in winter and in more northerly latitudes.
Altitude: 15,000–25,000 m; (49,000–82,000 ft)Appearance: Glowing brightly with vivid iridescent colorsClassification: OtherAbbreviation: PSC

I would think that because of the looks that this is Lenticular Clouds but they are also much smaller in the looks. Oslo is a Polar capital. So because of much colder air in the Oslo area, they are thinner yet very rare to spot. They are much smaller but some sort of particles gives the edges this specter of colors. The colors can also be seen when Stratospheric nacreous clouds show up. It seems to have the same specter of colors but they don’t look the same at all.

Interesting to see them. Once I have a clear answer to them. I will update this article. So, What type of clouds do you think that they are?
