2021-06-05 Noctiucent Clouds Display 3
Noctilucent (“night-shining”) clouds are the highest in the atmosphere, at around 75-86km altitude. They only appear in the summer months at latitudes between 50-70° (north or sourh), when the sun is more than 6° below the horizon.
Formed in the mesosphere at very cold temperatures from ice, dust and water vapour, their gossamer threads undulate and shimmer in shades of electric blue.
I spent a happy hour out in a nearby field watching the display come and go, the tendrils of cloud expanding and moving in complex abstract patterns.
