I looked out just before I went to bed last night at about 12.50am (11.50 UT) and spotted a few bright areas in the heavy cloud. Could NLC shine through if it's bright enough, or did I just see lights from the ground reflected on the clouds? On the first image the bright area is to the left of the pic behind the chimney, on the second it's over to the right/centre just above the rooftops. I think I already know the answer lol but just thought I'd check    Jo x |

Theres certainly a brightening toward the horizon, I see what you mean tho, but whether these are NLC I really couldn't say.
You do appear to have snapped some mammatus (sp?) clouds I think. These form on the base of a cumulo nimbus cloud as the storm cell is decaying.

Shame the government hasn't spotted this little blight on the national carbon footprint. I keep my fingers crossed one day the government will finally twig they could make an improvement on saving energy and carbon footprint etc by turning not necessarily all, but some, streetlights off after a certain time at night, or by going for better lighting design. Unfortunately i feel media scaremongering about crime will never allow this to happen. Perhaps in the next solar maximum we might be lucky and have a huge solar storm that knocks out the National Grid for a couple of days letting us see the night sky uninhibited - sods law says if this did happen it would do so when its raining...  |

When the stormy Emma cyclone visited us in winter we had an power outage for some hours. I went working for night shift, and when I was waiting for my bus I could see more stars in those five minutes than in the past ten years together... |

I did wonder if these might be mammatus clouds but didnt wanna ask because I really don't know enough about them lol. They look very different on the photo to what they looked to the eye, they were black with grey edges and looked veryyyyy spooky  Jo x |

Okey doke, mammatus clouds look slightly more intimidating than those Jo took a picky of - not heard of undulating clouds before... *starts a google search on them* |

Strange  Jo x |

Pilot hat on: I'd say those clouds are less than 1000ft up - there was quite a lot of the same kind of stuff around Anglesey at the time, too. I've always wondered how pilots guage cloud height - is it an 'experience' thing or is it something in the 'learning to fly book'? |

LOL I didn't say that was a techical term  I call them undulating as there is turbulance and instability leading to a not so smooth base to the cloud like rolling hills or sand dunes. Mammatus however, when you see it makes the hairs on the back of your neck stand up as they are awesome and usually associated with anvil clouds (storm clouds). Here is an example of them www.midlandsweather.org.uk/photopost/showphoto.php?photo=1063 |
