NLCs in Oxfordshire, 23rd June

[The Admiral]

Checked the sky after the late night news, and could they be NLCs? If so, the first I've ever recognized as such. Well chuffed. Taken around 10.45pm; they'd more or less faded by 11.00pm. I have a lousy Northern horizon, and so these were taken from upstairs windows.

Cracking display, wasn’t it? Great pics.

Nice shots!  I’m just over the border in Bucks (near Thame) and, like you, snapped this display just before 11 last night from an upstairs window.  They were so extensive that I wondered if they really were NLCs.

Thanks. Me too, particularly as I've never been aware of them before. I wasn't quite expecting them to extend as high as they did, more like a display near the horizon.

Thanks Paul, I just wish I had your scenery! Given their supposed height, of around 80km I believe, would we have been looking at the same clouds do you think?

Yes I suspect so. I’ve tried marrying up my images from the same time as yours and there are similarities definitely.

Well caught, had a short display here before they were hidden by  "real" clouds.

I was looking at the 'daisy wheel' for NLCs on the spaceweather.com site, and this is what I got today (but dated 22nd)

I would guess that the patches seen over the Northern parts of the UK were what were observed on 23rd, yet the dates are wrong, but there is nothing else seeming to be upcoming. I gather that the wheel rotates clockwise anticlockwise with time, but I think I need to get to grips with what this display actually means. I've found http://lasp.colorado.edu/aim/index.php so that might be a start.

Well, if I follow this correctly, it looks as though the satellite coverage rotates anticlockwise, but the vortex itself rotates clockwise. A link to an interesting video animation can be found here: http://lasp.colorado.edu/aim/download-data-L3B.php
