News Letter 4 Nov.99 Light Pollution is a growing threat to the night time environment one that has already harmed astronomers.
Glare is never good.
SKY GLOW - a brightening of the night sky caused by the scattering of artificial light by water droplets and dust in the air. In 1997 power stations in South Australia emitted about 9 Million tonnes of carbon dioxide, and produced about 325000 tonnes of fly ash and over 12500 tonnes of sulphur dioxide in the same period. There are solutions to the problems. Quality lighting is the key. These solutions preserve the dark sky for all of us, improve the quality of night time lighting for better visibility, better safety and security, more attractive surroundings, and save money as well, for we would use the light rather than waste it.
