Noctilucent Clouds (NLCs) 2017-06-15

It’s just a week off being the longest day, and it seems never to really get dark at night around here at the moment. Still. While that precludes shooting the aurora, instead it’s noctilucent cloud (NLC) season – just started in the past couple of days so I was very pleased to capture these last night / this morning around 1am.

Apart from being a canary for global warming, NLCs are a beautiful phenomenon, glowing cold bluey-white typically filament threads lighting up the sky. Or, if you leave the camera thinking for 2 minutes they blur nicely with the more mundane clouds:

And I made a short timelapse – 6 minutes compressed into an 11-second video:
