NLC's were observed this morning 0200UT to about 0235UT covering a wide area of northern sky. Nothing too impressive though. Will post an image later.

I seen that display too John, I could see two sections, in the N and NW, about type 2.5 brightness, structure was like a patch of veil or 'surface' with long blue wisps in the NW. I seen in it through cloud and murk but it looked like poor display. Still, good to see one on the same evening as the volcanic dust display.

This is one of the images I got this morning (July 4th) at 03:02BST. 4" f5.6 ISO 800. Not all that impressive but still a display to note.

July 04/05: Negative in the evening, a nice but not spectacular display in the NE in the morning - centered around Capella but running up to approx. 25 degrees elevation at 0245 GMT. Bands but no swirls, characteristic electric blue colour, anyway the sun was still far enough down not to be able to illuminate stratospheric dust. Bright twilight arch was faintly coloured orange/red/purple (by volcanic dust?) but much interference from tropospheric cloud during the "volcanic sunset/rise" period.

Great images Jonathan, I love the shot with the car trail, very cool looking  Smiley

I can confirm your observation Brian. NLC display was poor during the evening but before dawn it turned out rather nice as a type 3 brightness display over 20 degrees high with veil, small scale whirls, very faint herringbone, and IIb bands casting their shadows onto the veil higher up. The bands looked more like ridges or fine folds in a blanket. Watched it until 03.30 BST but didn't take any images.

At sunrise I observed a very colourful volcanic dust display, a strange pink-red colour with structure and rays. Again, I didn't take images because I was knackered so just a visual observation. Quite an exciting 24 hours with thunderstorms, volcanic dust displays, and NLCs. The night sky was interesting also with a nice ISS pass which was chased by a supply vessel. Observed two flares which may have been a spy sat cluster very close to Jupiter moving in a vertical line down towards the planet which looked incredible!. Some meteor activity observed also. The nights are getting noticably darker that's for sure.

What a nice delicate NLC structure you had there last night!  Smiley

Today, after a long break I've seen an NLC report from Sumy (200km N from Poltava) of Jul.03 evening. And here the sky was cloudy with rain.  Sad

Thanks Roman.

This is another one from this morning, and I found this very interesting because of the large patch of wavy structure that stretched right up to the zenith. It stayed there until the sky got to bright and it was drowned out. This is looking roughly NNE and the bright star above the house is Capella.

Keep imaging them Padraig!  Smiley

IMHO in that case you should choose smaller ISO value and several times longer exposure.
