Hi,

It seems that the bright nights are putting a dampner on the discussions a bit :-)

I noticed reports on other forums about notilucent clouds, which apparently are most visible at this time of year, though I must admit I've never seen any.

Some images: www.meteo.helsinki.fi/~tpnousia/nlcgal/nlcgal.html
FAQ: www.nlcnet.co.uk/nlcfaq.htm

Has anyone here ever managed to see or image this pheonomena?

Cheers,
~Al

albert,
i am sure i saw something like that last night from about 10.45 ut to about 11.05 ut. at first i thought maybe there was an aurora due but i didn't remember getting any warning emails. it started in the nw and moved across the sky to the sw as far as vega and it was there about 5 or 10 mins before fading out. then i saw somemore below the pole star and this went on until about 11.25 ut until it finally faded away.

And the fact that most of the planets are gone for a few months :cry:

Folks, I've only managed to see these once in June 1997, low in the northern sky. I'll never forget the sight, beautiful wave like very thin clouds with all the colours of the rainbow!! - red green, yellow, blue, silver.....They are caused by sunlight scattered off very high (cirrus) in the atmosphere, I think that they are frozen ice crystals in them. It was somethin' else, but I never got a shot, I did'nt even have a camera then. Look out for these over the next few nights.

Keith...

I added several photos in the files section of Noctilucent clouds i took in July 2002, all on the same night from Mayo at around 3am. Exposures were a bit too long and clouds were a bit over exposed as you can see.
