cloud of nacre

Blue tide, glowing mushrooms, rainbow fire ... are strange natural phenomena, rare to witness.

The dark black sky of the polar region in winter is not only the backdrop for the northern aurora bands, but also the presence of an equally natural phenomenon named nacre cloud.

Just before the sunrise on December 9, the lucky people on the island of Scalpay (Scotland) have witnessed the spectacle of the cloud shining with nacre color.
