I got these in Wallsend after noticing the unusual sky colour and
lightness. The camera had some difficulty in picking up the strange
colours but a quick tweek in Irfanview did the business.

Enhanced have _contrast in the filename

sunset showing strange hazy clouds and strange reddish halo / rainbow

http://llandru.servehttp.com/strange...5_contrast.jpg
tweeking the contrast shows nebulous high level cloud

http://llandru.servehttp.com/strange_light/P2180886.jpg The bizarre
skies and weird clouds are evident in this south facing pic. The cranes
are what's left of the Swan Hunter shipyard.

tweeking the contrast shows altocumulus or cirrocumulus at very high level.

cloud holds focus and is very detailed. Image was taken at 1650z.

Applying high contrast gets me this. NLC observers will recognise this
immediately! It's obviously high atmospheric but very complex.

Unusually light and orangey across sky and houses so later after
sunset.
1745 East Yorkshire.
Despite 7 oktas stratocumulus at 5000ft (sc perlucidus), the pink
glow was very much in evidence shortly after sunset here here on Fair
Isle. It was very much enhanced by the haze reducing the visibility
to 12km.
Rather interestingly, just before sunset, the sky took on a very pale
lime green colouration that slowly faded to be overtaken by the
orange glow at dusk.

Do you think that was a green flash? http://en.wikipedia.org/wiki/Green_flash

Too long a duration for a flash - lasted about five minutes. But I
guess it could have been a similar phenomena - differing refraction
of light of different colour (wavelength) by the atmosphere.

I thought the visibility had to be very good to see the green flash?
I've seen it a couple of times outside the Old Success at Sennen near
closing time. Both times it was very clear and I was specifically
watching for it. It lasts just 1 or 2 seconds as the final bit of sun
disappears.

I took this photo from the Control Tower at around 1745Z, but really wished
I stayed on another 10mins, as as I was walking back to the car, it turned
into a brilliant orangy-red but alas no photo opportunities....

Hello Graham
Yes, I recall (just about|) seeing green flashes (and blue ones) around
closing time at Sennen Old Success some years ago.
Do you think it's the local atmosphere?

Hi Peter - there seem to be quite a few people from Sennen following
USW!

I always assumed it was the very clean air that made it visible, and
looking west from Sennen there isn't much to cause pollution.

However, layers of undisturbed warm/cold air over the sea surface at
night might play a part as well.

All the best
