[ATMoB-discuss] Noctilucent Clouds

[noatak at aol.com]

I'm curious as to what people in the club think or know about Noctilucent Clouds.

There have been a lot of reports of sightings of these mysterious clouds which form in the extreme
upper atmosphere and are typically visible 1-2 hours after sunset in the summer months. All of the reports
lately tend to be from observers in europe and a couple last month in the Western US. Nothing here however.
Anyone wish to fathom a guess or post a logical reason why these might be occuring there and not here.

Is there a web site dedicated to this phenomenom that would allow a search of past occurences and 
corresponding locations by date?

Has anyone seen this lately from the Eastern US?

I do hope we get a display (on?a clear night). I would love to see what appears to be quite an impressive
sight rivaling a good auroral display.
