Good clear sky here at the min...

Thanks Brian, just back from imaging, got some good ones, loads of structure in that display, and yet again some strange formations I have not seen before. Off to get some kip now so will post images later.

The display was a bit unusual - broad bands with only faint rippling - but definitely unmistakeable for anything else. Persisted in the Auriga region until at least 0245 BST, some interference from convective cloud later in the night - I got rained on, I'd forgotten it could do that! Interesting to me was that the max height of the display declined until local midnight (approx. 0120 BST) then started to increase again. Once again I noticed a brightish patch, apparently isolated from the main display, in the NE towards morning.

Got a good bunch of still frames - here's the video, slightly affected by Jude part closing the window part way through, but the action isn't affected!

Looks like you guys got some great results last night! (I'm jealous! Tongue)  You seem to be having the run of the weather, although clear skies are potentially predicted for me tonight, so, fingers crossed! Like those HD vids Paul, they work really well  Cool

Yeah Mark we had a great display here this morning. Of interest was a row of holes below Capella and some circular patches of ripples to the east of. I have never seen these forms before. These images are untouched except resized, and are in the order of 8-10 seconds at ISO800.

Brian, thanks for the heads up last night. I had alot of cloud in that area so couldn't be certain from here as all I could see was a faint glow to the SE of Capella, then it cleared abit more after 00.30 BST and  that was when I could see NLCs for certain. I watched the display until after 03.00 and noted that strange detached segment in the NE which was notably blue. Seen bands, veil, and extremely well defined waves/herrigbone arranged in dramatic clusters below Capella before dawn. I seen those convective clouds on the northern horizon bubbling up and thought there were showers falling in that direction, which Brian and the radar confirmed, however all throughout the session patchy trop cloud hid the best part of the display. I had trouble getting my camera focused too so haven't resized the images yet, hopefully will get to rescue a few of them. Good to see another display again!!, type 3 brightness, 80 degrees in azimuth and 15 degrees high.

Paul, great timelapse, that's the first of many spetcacular results to come!

John, great images, the last one really captures that display of herringbone very well, lovely results as always.

Mark, keep watching tonight, this could be the start of a 'burst' of NLC activity over the next few nights  Smiley
