Noctilucent cloud season for the northern hemisphere kicked off in the first week of June. But poor weather and travelling meant that I only saw my first display of the year last night.
Here are a few pictures taken from Amble and Warkworth.
Noctilucent clouds (NLCs) might have a passing similarity to cirrus clouds but they are very different. They form about fifty miles above the ground in the mesosphere and are seeded by meteor smoke. I've written in more detail about them previously. The display last night was terrific and was still going when I got to bed at 1.30am.
