Lately, Arctic sky watchers have been seeing a lot of Polar stratospheric clouds.
And this time, Andy Skinner captured an eerie moon stratospheric cloud in the sky over Abisko, Sweden.
These is neither a space nebula, nor some dancing auroras around the moon. No those are “nacreous” or “mother of pearl” clouds forming in the lower stratosphere when temperatures drop to around minus 85ºC.
Another awesome sight of polar stratospheric clouds that I have never seen by moonlight before.
