Nacreous clouds

I had nice suprise, when I was returning to Espoo from "digikuvaajat" meeting held at Hauho. Sun was setting behing the treelines, and sky was colourful. Low in the sky at direction of sunset, there was some wavy clouds visible. Nacreous clouds !!! It is first time for spotting them in 2011. Latest really beutiful nacreous clouds, I have seen man years ago (too long in my opinion). If I correctly remember, it was 1995.
