#OTD a year ago, I walked out of my office around 23:30 to ride home & was stunned by the display of noctilucent clouds overhead

I took *a lot* of pictures with my phone: Iâve reprocessed some for the anniversary. Enjoy

The first two 21 June 2019 #noctilucentclouds photos here are similar but not the same â you can see the evolution over 2.5 minutes. The third was taken in Katwijk ~35 mins later, as the clouds drifted over the North Sea towards the UK.

It was by far the best display of #noctilucentclouds Iâve ever seen: normally they appear low on the northern horizon & even then, theyâre rare. That said, itâs said that theyâre becoming more common, so keep your eyes open & follow @NLCalerts

Thereâs plenty of information online about how these rare highest of ice clouds form at 75-85km altitude & also the remarkable fact that theyâve only been known since 1885. Their increased occurrence may be linked to extra methane in the atmosphere.
