A view of distant nacreous clouds, captured with the tail camera of a Glider at 50,000 ft. over Argentina.

Beautiful cloud picture, Morgan!
Definitely flying the glider very high up in the sky with all the mid-level clouds located far below. Can imagine how cold it would get at 50,000 ft (near the bottom of the Stratosphere), despite the sun shining through the very thin atmospheric air up there in the glider- probably as cold as -50C at least. The distant, rainbow nacreous cloud captured by the glider’s camera would be located even higher up in the very thin atmosphere where it is even colder and would be entirely made of ice crystals.
