Earth Hour

"Twenty-five cities around the world are confirmed to take part in WWF's Earth Hour"

.... and none of them in the UK. This initiative needs more publicity to raise awareness of the issues concerned.

Earth Hour

Definitely a good idea to raise awareness of light pollution and energy wastage issues. However we must make sure that by switching lights off we don't resort to candles that would increase the carbon footprint despite the lights being turned off. Apparently, I'm told, the carbon dioxide released by...

Light Pollution, Global Warming and the environment

Dear Astrotux and Cliff, So what causes global warming? It’s the increased carbon emissions from the combustion of fuels used for transport, lighting (streets, commercial, domestic and security), heating (domestic and commercial), transport, and industrial production. As I see it the rise in CO2 l...

The ecological effects of Light pollution

This is something about which I have been trying to raise awareness for many years. In 1994 I published a letter in the BAA Journal outlining the ecologic effects of light pollution: http://articles.adsabs.harvard.edu//full/seri/JBAA./0104//0000313.000.html In this article I pointed out that this wa...

Aurora blackpoolensis

Dear Cliff, The CfDS is already working on this one, so maybe something will get done. I also contacted Blackpool Astronomical Society alerting them to the problem but have not had a reply. I don't know wat it is with these morons. Why this propensity to light up the universe in the name of "regener...

R CrB 2007

I have been following R CrB from May onwards, from Tabuk in Saudi Arabia. It remained steady around 6m.0 until June 23rd when I noticed it had faded to 6m.2. I sent a text message to Guy Hurst informing him that it was marginally faint. In a subsequent phone-call we decided not to issue a genaral al...

Non astronomers

Dear Cliff, I know what you mean when it comes to discussing street lighting with non-astronomers, and it can be very frustrating. However, I won't let that put me off. I know I'm right and they aren't, so I will carry on regardless, using all the avenues at my disposal. This includes the CfDS, and ...

Lighting and crime

Dear Andrew INT Thank you for your message. This just reinforces my original assertion that lighting does not reduce crime. This fact needs to be communicated in a big way to the general public who still seem to think that floodlighting everything will keep criminals at bay. I doesn't. In fact they ...

Energy constraints

Dear Cliff and Astrotux, Greetings from Saudi Arabia! Yes, I'm fairly sure it will be energy constraints that will win through in the end. The profane have no real concerns about the doings of astronomers and couldn't care less if their view of the sky is compromised. However, if it stopped people w...

Joe Public and lighting engineers

Dear Cliff, Only too sad and only too true, but I remain undaunted. I feel there is a needed to raise the profile of anti-light pollution activism amongst amateur astronomers nationwide. As we have seen with the Stockport Skybeam and the Southampton Laser Gateway, activism does work. It's a slow pro...

Street lighting and crime

Hi AstroTux, You have made an excellent point. Most crime occurs in daylight Increases in street lighting that we have experienced over the last forty or fifty years actually makes people behave at night more as they would during the day, so one can expect that intensively lit areas will have a high...

Southampton Laser Gateway

I am pleased to announce that the proposed project to install four giant lasers in the centre of Southampton has been abandoned. New council bosses finally conceded that it was probably an "ill conceieved idea" that would impact negatively on neighbouring communities, and that there was no appetite ...
