Nacreous on the way?

In his Weather Eye column, The Times, 12JAN11, Paul Simons says the warning signs have been detected in the stratosphere over the Arctic. Apparently Europe had intense easterly cold in 2/09 and 2/10 with fabulous mother-of-pearl clouds shimmering after twilight (I didnt notice them). The signs say it could happen again this year (no surprise to GWW). An example:

Thanks for the link. Lovely photo of naceous clouds! We'll all have to keep a lookout for these beauties in February. Just to prepare us, has anyone got hints for photographing them? I presume they need a long exposure? GWW

I saw my first Noctilucent clouds over Northern Tasmania last week. Full night sky, well after sunset with streaks of luminous greenish under the stars

Nothing too spectacular... just for the record.

As they occur just after sunset and the sky they are in is still pretty bright, you don't need a long exposure. In fact, I would slightly under-expose meaning your shutter would be on the faster side. It's easy to photograph sunsets with the camera hand held after the sun has gone down but you might need a tripod as it gets darker although resting your camera body on anything stable and still will suffice. I photographed the last main nacreous cloud we had here back in february 1996. It was a spectacular one too. I only had my 35mm camera at the time. I'd love to see another and photograph it with my current camera.

It was a very windy evening that day I remember.

Here's a rubbish scan of one of the pics I got. you can tell why I'd like to get more:P

Just to add that there was quite a bit more of it further to the left of the shot. I couldn't fit the whole lot in because it was too spread around.
