Over Europe began to Shine noctilucent clouds

Observers in Europe misleading misleading about the spectacular explosion of silvery clouds. Very bright noctilucent clouds was in Gothenburg, Sweden, June 13. Almost every night noctilucent clouds getting brighter, as the Northern summer comes into its own. Electrically blue cloud was seen in the last days also in Denmark, Poland and Estonia.

Recall that NASA noticed the first noctilucent clouds of the season 2016о year on may 24. These first clouds were thin and weak. Now display of noctilucent clouds was powerful and bright.

Noctilucent clouds float at the edge of space at more than 80 km above the surface of our planet. They are filled with tiny ice crystals. When the sun rays fall on crystals, clouds glow electrically blue.
