Light pollution in the UK
What is the status of any public uproars (well, public uproars only in
the astronomy community, that is!) on curbing this *disease* that's out to ruin all future stargazing fun for amateurs in the UK and worldwide alike? Has there been any serious legislation proposed/drafted to control this problem going forward? Has anyone proposed forwarding a million-signature petition to Tony Blair yet?! I don't think he's into astronomy personally... if he were, he would have prevented a lot of it a long time ago. Is there ANY politician who is a keen astronomer or has a strong bias in favour of astronomy? Probably a topic that's been on everyone's mind, but the problem in Luton is just getting worse and worse. Abdul Ahad |

Immediately to the front of my garden there is a foot and cycle "Redway" which has its own lighting; a little further away there is the road on which I live with its own lighting, About 100m in front of my house is the A442 dual carriageway (H3), and a shorter distance to my right is a single lane road (V9). Both these have lighting different in colour to the Redway and local road. And finally, there's the roundabout where H3 meets V9. That has brilliant "white" metal halide lighting (I think). My back garden is better, particularly in summer when the trees' leaves screen the lights on V9, but my neighbour's eucalyptus has grown enormously in the last year, and I can no longer view to the S at any sensible altitude. I have taken my ETX105 to local "dark sites" (about 10 miles away) and was disappointed to find that, using my EOS10D, that the sky background whilst appearing dark visually, was only about 1/4 the level seen from my garden*. (give or take lots of experimental error g!) * based on exposure time for similar orange glow. -- M Stewart Milton Keynes, UK http://www.megalith.freeserve.co.uk/oddimage.htm |

I understood that as of January 4th this year light pollution is required
to be stopped by law if a person complains that the pollution spills onto their property. This applies to street lighting. However, since I havent seen anyone use this law I wonder if it actually came to pass. Anyone know? I fly airliners for a living and am always amazed at the amount of light we send to space. maybe councils havent heard yet, but we dont REALLY follow roads! david "AA Institute" wrote in message oups.com...

I long to see the Milky Way dipping out and into the Channel from the Isle of Purbeck. At Milton Keynes Astronomical Society, our scouts have found a reasonably dark site near Thornborough. Good for constellation imaging and meteor observing. Pierre |

Abdul,
There was an enquiry held by the Science and Technology at the House of Commons 2-3 years ago about Astronomy and Light Pollution. The conclusions they reached were encouraging but you'll have to wait some time before you notice anything different. You can now do something about your neighbour's 'Rottweiler' security light under a bill that came into effect earlier this year. Somehow, local councils are not included in this and they have adopted instead a policy of improvement through renewal. This could take years..... Pierre |

That sounds really promising, if such a law actually applies. Thankfully my garden is not directly in view of any street lighting, as it overlooks a railway line at the back. But I am concerned about the total amount of unwanted light that the town as a whole throws up into the sky. We have Luton Airport expansion plans on the cards too, and that can only make things worse in the future. For me, the biggest loss over the past couple of decades has been in star colours. At one time, Betelgeuse used to look deep red and Arcturus was a solid orange. Now the colours have really faded. Arcturus appears yellowish at best, and not to mention the rich Milky Way starfields around Cygnus. A casual binocular sweep on a summer's night then would show the deepest concentration of stars - literally "clouds" of them - with occasional red/orange stars looking nicely contrasted against the blue-white ones. Now, it's all looking very thin and colourless... and it's not down to my aging eyesight, because photographically it's the same! However, since I havent seen anyone use this law I wonder if it actually came to pass. Anyone know? I fly airliners for a living and am always amazed at the amount of light we send to space. maybe councils havent heard yet, but we dont REALLY follow roads! I wonder if there is such a thing as a "light pollution index" (LPI) measure for the UK? Example: 1980 LPI=100.0; 1990 LPI=145; LPI=175, etc. Such a measure could be obtained from an Earth observing satellite passing over the British Isles and measuring total stray light thrown up from all of the bulit up areas at night, up and down the length of the country. Greater London would no doubt account for 80% + of such an LPI index for the whole of the British Isles... It would also enable a quantitative gauge on how bad it's really getting over time. And if any caring authority really wanted to keep light pollution under control, it could set targets like "LPI reduction of 20% by 2020, 25% by 2050", etc. Abdul Ahad |

On energy efficiency grounds, householders are now required to fit only certified double glazing (or pay a council official to certify it). A proactive policy on public lighting would cost money. (It's all about money really.) -- Hil |

At Milton Keynes Astronomical Society, our scouts have found a reasonably dark site near Thornborough. Good for constellation imaging and meteor observing. Pierre I understand that the replacement of the older sodium D line lamps by the wider spectrum stuff is driven by the the requirements of CCTV and witnesses to crime (so that their descriptions of their assailants clothing colours are more accurate). Try the GE street lighting website for more info. There's a new housing estate on the V10/H7 area that is being kitted out with near white domestic street lighting. Coincidence? The "dark site" where I did my checks was just outside Thornton in a field on the road to Thornborough. -- M Stewart Milton Keynes, UK http://www.megalith.freeserve.co.uk/oddimage.htm |
