Mid February this year PSCs were seen quite widely in countries bordering
the North Sea - I can remember posting here about curious sunset colours,
which was confirmed by some others.

One of the authors of a paper on these clouds (Weather, April 2009, p.87-92)
would like anything we can add.

Is there an archive of our postings?
Have you still got a a copy of any posting or observation you made
concerning coloured twilight skies or noctilucent clouds?

If "yes" would you please EMAIL them to me for forwarding.

Regards
