Rather more cloud than you
Yeah, that looks like the lot that moved in on me after my VS session terminated at 0230 BST due to increasing sky brightness. I was hoping to image Jupiter when it got round to the south but the seeing in the patches between the cloudlets was abysmal - Jupiter's limb looked like a Guernsey 3d bit most of the time, and it was impossible to see anything other than the major belts. Annoying as the seeing had been pretty steady during the "night".

Very nice images guys, Brian the display you got looked alot better than what I saw here.  Smiley

Observed NLC display from 01.20 - 03.30 BST, peaked at type 3 bightness with white/slight blue coloured herringbone, with soft-edged/diffuse bands and whirls all visible in advanced twilight. Didn't take any images, it soon became mixed up in alto cu trop cloud. Venus however looked spectacular low in the NE being very red in colour due to atmospheric extinction.

I have some snaps from the timelapse camera - OK, but nowhere near last week's displays. Will post later.

Here's another one of those ripples taken a few minutes later. Just before they were washed out by the dawn some of that "stuff" at the top of the image was over near the zenith.

Hi Tyler, look in the twilight arch when the Sun is between 6 and 16 degrees below the horizon, any time when the stars appear within the twilight really. Don't worry because if there's a display visible then you will certainly know it, especially if it's a bright one. Keep watching, you could get lucky some of these nights!

June 24/5: NLC negative but there was a persistent band of tropospheric cloud / sea fog? low in the north east which may have hidden a minor display.

Very minor display observed from Maghaberry, some ripples and waves but nothing special. Got a couple of images just to record it. Max alt about 2 degrees below Capella. Thick low cloud rolled in and put an end to observation.

Hi Tyler, I've been chomping at the bit to see some NLC's from here in the States too, I just don't think it's going to happen. You're at about 41 N latitude and I'm at about 42.5 N, I think we're pretty much outside the realm of visibility, not to say that it's not possible. I read somewhere that 45 N is about the southern limit, give or take a little. Having never seen any, I relly don't know what I'm looking for either. Everytime I see something  after sunset it turns out to be just high, thin cirrus fading very quickly with the sunlight. I'll just have to continue enjoying the marvelous NLC images on the forum.

Observed a poor NLC display last night (June 14/15th) between 01.00 - 02.00 UT in the NW to NE sky which reached 7 degrees above the horizon. A small patch below Perseus was glowing gold with a peak brightness of type 3. The display rapidly faded to type 1 brightness then spread out in azimuth sporting white veil and soft band structure. A group of well defined waves/herringbone formed below Capella before dawn. Not a very good display at all so I didn't take any images, however it was still an NLC display all the same. We are over due another round of big displays any night now.

Hi Richard, I think it's possible to get a display from your location, keep watching and you might get lucky.

I got a few images last night (June 24/25) but as Martin says it was very umimpressive for the middle of the NLC season. This image was taken at 02:40BST and shows that structure below Capella (bright star upper right). It was quite murky lower down and had it been clearer it may have looked brighter.

Richard, Tyler, just to compare: some recent NLC were seen from Romania (44-45N), Kazakhstan (42.5N) and Spain (41.5N).
And I remember early July last year when there was a display visible from Turkey and Iran (39N)!!
So keep watching, you might get some of them.  Smiley
