We saw the most magical sight this morning in Bergen. At first we thought they were daytime Aurora Borealis but it's more likely they were a rare sighting of nacreous clouds, polar stratospheric clouds which form only below -78C and sit 3 x higher than airplane cruising altitude.
They were seen yesterday in parts of UK too
