Hungary had a major display - just many places were obscured. :-( I was lucky to see most of it through a big cloud gap at the right place. users.atw.hu/egbolt/DSC_6302.jpgMore pics and animation would come in the afternoon ( I have to go to work).

Hi, That's a fantastic picture. The sharp edge at the western side is very interesting. I'm looking forward to seeing the animations. Regards, Bill.

Wowzer - I was out last night, but too much cloud cover. There was a small break and I thought I saw some high up. I discounted it because of the height from the horizon. That is a fantastic capture.

Hi,
Research done by scientists from Sweden/Russia indicate that these "walls" are significant boundry zones and to be this sharp is quite rare. It might be related to how gravity waves break in the mesopause.
There have been another couple of good displays seen over the past two nights but they don't have these sharp bounday zones. They are worth watching out for especially from a location like yours which is just a bit further south.
These are the formations that might be home to the structures I call type L. These unusual structures are very interesting to watch.
Regards, Bill.

Hi, Thats a great shot too. It's interesting to see the "twinning" of some of the structures almost like double bands.
This is why I recommend people always have a look at NLC with binoculars as the fine detail is extraordinary, especially along these boundary walls and other dense areas. It's almost fractal, you can see feature on top of feature.
As they generally occur only a few times each season they are good to keep an eye out for and on!
cheers, Bill.
