Noctilucent Clouds

Late night on 10-June-2013 I looked out from my window on the MV Explorer and saw Noctilucent clouds. I had read about ( , but never seen Noctilucent clouds before. The clouds are ice crystals that are very high that you can only see for a short time when the sun is below the horizon. We were in the Baltic Sea traveling from Stockholm in Sweden to Copenhagen in Denmark and the sun doesn't set until very late I set up a camera in my cabin and took a set of 99 images that I made into this time-lapsed video (Nikon D4, 28 mm f/1.8 lens (ISO 200, 28 mm, f/1.8, 1 sec)).
