I have seen a lot of Noctilucent clouds over the years, but this morning's was by far and away the most ominous. At 3:00am our bedroom was completely lit up by this show.... Best watched full screen.
This morning we had the first Noctilucent Clouds of the season put on a show....
Some of the interesting facts about Noctilucent Clouds are covered in Scott Sistek's blog this morning. The Noctilucent "season" is active about 3 weeks either side of the Summer Solstice.
