They're visible when fading light at sunset passes through tiny ice crystals blown along by a strong jet of stratospheric air. The colours are reminiscent of the colours which reflect from a thin layer of oil on top of water, an effect known as iridescence. The colors were spanning from white green to violet red color.

Some really rare clouds were spotted in Oslo (Norway) that I have never seen before. Special reactions that occur on PSCs, combined with the isolation of polar stratospheric air in the polar vortex, allow chlorine and bromine reactions to produce the ozone hole in Antarctic springtime.

Ice polar stratospheric clouds (nacreous clouds) form at temperatures below the ice frost point, typically near −85 °C, which is colder than the average lower stratosphere temperature.The characteristic bright iridescent colours, resulting from diffraction and interference of light waves, suggest that the clouds are composed of similarly sized spherical crystals of about 10 μm in diameter.

I would think that because of the looks that this is Lenticular Clouds but they are also much smaller in the looks. Pitts said mountain wave clouds at such high altitudes are rare because they only form when the jet stream is properly aligned with the edge of the polar vortex, a large air pressure system over the poles. On the 24th of January 2020. Specifically, the clouds form surfaces where chemical reactions can take place that produce ozone-destroying molecules, and can contribute to the formation of polar ozone holes. The clouds are usually seen over Norway and other polar regions, when the sun is just below the horizon so it's a rare treat to see them in the UK. After doing some researches.
