Spotted another NLC display last night (June 29/30th) high in the north some 22 degrees above the horizon in the form of type 2 brightness silver type IIb sharp edges bands and IIIb waves with undulations located well above Capella. Had it in view from 23.10 - 23.20 BST then clouds arrived.
Very nice captures, particularly those first ones Eric which are really expansive.
I saw a display last night but due to immense tiredness only photographed them from my landing window which makes the images a bit poor. Although judged against the lights of my town these were moderately bright with some structural detail seen, particularly in two brightish bands to the west of Capella.

In the morning of Saturday June 30th I observed very nice noctilucent clouds from Toulouse, southern France (!) The display was pretty good and became easily visible even to beyond the 28mm lens field of view (on full frame) after 3:22 UT to over the zenith somewhat later... although much more diffuse. At 3:45 UT I noticed some patterns in very low contrast to the other side of the sun. No cirrus was present when it became day (only much later). I have made a photo series including some modest timelapses, but right now I am coping with a harddisk/boot problem that I need to fix. Expect the images tomorrow or later this week on my website
I caught this NLC too from Scotland but from here it seemed to be a fairly average NLC. However, I've just noticed that it was observed from Portugal and if I've identified the location correctly the latitude would be 38.5N. I've never heard of NLC being observed that far south from Europe. Makes me wonder if it could have been visible from North Africa - Northern Tunisia is 37.2N, for instance.

I have posted the photo series to the Aurora & Noctilucent Clouds gallery on my website: www.lightningwizard.com/AurNLC.php Two short animations will be added a bit later (one a bit contrast enhanced... shows also small whirls, type IVa if I'm not mistaken). You have to excuse me for the slight horizon tilt (ah those early mornings...) The cropped composition involved with straightening usually annoys me even more than the tilt itself, so I left it this way
