Nacreous Clouds

We have had a spot of cold weather again with temperatures dropping to -16˚C (3˚F) during the night. One afternoon, as the sun was setting, some features started to appear which indicated that nacreous clouds could be present. Nacreous clouds, or "mother of pearl" clouds, are a type of clouds forming in the stratosphere at altitudes above 15000m, and just after sunset they reflect the sunlight and appear to be glowing as patches of mother of perl. I grabbed my camera and rushed of gambling on my hunch being correct. Perhaps not the most spectacular specimen, but at least I did not make the trip in vain. Hope you like it.
