Fab noctilucent clouds
 

If anyone's awake in Scotland look to the north for a fantastic noctilucent
cloud display. Sky goes from deep dark blue abruptly to strong bright pale
blue clouds. At the boundary are very clear wave formations, these may be
presence/absence of cloud waves but it may well be that the wave peaks are
just high enough to catch the sun and the troughs are not.

Will post photo links soon

NLC is still very visible azi 000 - 090 here in Wallsend, 55N. See other
post for photographs.

Aye, noticed it when I went to bed about midnight 2330z. Not as big as
the display early on the 14th June around 0145z. That was very big and
bright, not much detail and partly obscured by tropospheric cloud. I
did take some photos of that display, didn't of last nights though too
tired.

Yeah, we got a good view of this from northern Cumbria last night. The bit
to the north was a bit hard to see as there were things in the way, but
there was a nice display in the western sky as well. My pix aren't as good
as yours, but here's one anyway, looking across the Solway to Scotland.

I can't persuade my partner that there's anything special about noctilucent
clouds. He seems to think it's just the sunset lighting up ordinary clouds.
How can I educate him? Is there a good website I can send him to?

Any relationship to the calm after a storm?

I've put up a photo on uksevereweather (uksevereweather.org.uk) which shows
ordinary stratospheric cloud (stratocumulus castellanus) dark whilst the NLC
is white / light blue / pale orange, click "noctilucent cloud" in the left
hand frame. The splash pic has also been changed to the same photograph.

As for the relationship with storms, I always check for NLC after a cold
front clearance in summer but i'm not sure if stratospheric frontal activity
can really affect the air 50 miles up..... I read on the NASA website (or a
link off it) that NLC was first described after the Krakatoa volcanic event
and it's becoming commoner (due to global warming, hmm - more likely there
are more observers!).

Thanks for the photo Ally. I missed that display, and was away on the
14th as well. In all my years of staring at the sky, I've never felt
absolutely sure that I'm looking at noctilucent clouds. When I looked
just after midnight this morning, there were orange clouds in the north,
but I presume this was the reflection from Carlisle?

I'm looking forward to the eventual enabling of our exchange to
broadband, then I can do some real weather related research on the web -
so many good pictures to see, but a real pain on dialup.

Sometimes I'm not either, rather surprised that not much mention has
been made of the 14th it was very bright, nearly enough to read by...
not much detail mainly just a milky blue glow from about NE to NW and
up to 30 or 40 degrees. There where some swirls in one area.

I must do the geometry to convince myself that anything bright and
bluey white to the north around this time of year must be nocitlucent
cloud as sunlight tropospheric cloud would be below the horizon.

When I looked just after midnight this morning, there were orange
clouds in the north, but I presume this was the reflection from
Carlisle?

Possibly but the low northern sky at this time of year can have a very
red/orange glow but will have different shades of red/orange being
brightest nearest the horizon and fadeing to dark blue of the twlight
sky above. Light pollution is mostly low pressure sodium and doesn't
have various shades.

Nice clear night again...
