We are seeing beautiful "mother-of-pearl" clouds, nacreous clouds, ever so often as the January evenings darken. They are formed high up in the atmosphere where air temperature goes below -78C and actually are a danger sign more than being extremely beautiful, as they might indicate breakdown of the ozone layer.
The 85mm f/1.8 S-Line on my Z50. These clouds are so delicate in their colour appearance and any photo hardly can do their beauty sufficient service. However, the Z50 did came close.
