Noctilucent clouds appear where they were not expecting

Noctilucent clouds "descend" through the Arctic circle to the middle latitudes. As noted by Debra ceravolo who made this image on June 1, the Northern sky during morning twilight was shining brightly — it was decorated with beautiful blue-green clouds.

She took a picture of noctilucent clouds from Osoyoos in British Columbia in Canada — according to her, at this point (49 degrees latitude) of these clouds are observed rarely.

Noctilucent clouds stand out among the rest not only for its unusual appearance — they are the most high-rise on the Earth. These clouds are formed at the border of space, at an altitude of over 80 km Summer jet of water vapor rise into the mesosphere, and the water kristallizuetsya around meteoric particles.

Last summer noctilucent clouds spread far to the South, to Los Angeles, setting records observations at low latitudes. I will repeat something similar this year? It's only the beginning of the season, but they have already seen in many regions of Russia.
