Nacreous clouds of type I were observed during many days around mid-winter all over Finland. I was also once able to observe this phenomena! It happened in the evening of the Christmas eve in Ulvila, Finland. There was a gap in the otherwise continuous layer of low clouds, and the nacreus clouds were visible from this gap! The nacreous clouds were coloured orange by the setting Sun. I also observed some crepescular rays on the smooth veil of the nacreous clouds.
