Arctic Lights Around Winter Solstice

Here on 71 North, it is dark almost 24h around Winter Solstice; only around noon do we see some twilight. But sometimes light itself is spectacular, such as today when iridescent clouds coloured the southern sky. These clouds are typical for the polar areas and are formed 20-30 km up where the temperature is down to -80 Celsius.With light like this, who cares if it's dark the rest of the day?
