what measures you ask????
"Siding Springs is within the area of Tamworth City Council, which approved guidelines about outdoor lighting placement earlier this month. Outdoor lights are now required to have a shield that prevents any light being directed above the horizontal plane.
A spokesman for the Council explained the guidelines were an attempt to be more proactive about increasing light pollution in the area. People who do not comply will receive an advice letter."

Light pollution is considered to be every form of illumination by artificial light which is dispersed outside the areas it is dedicated to, particularly if directed above the level of the horizon."
I am starting to admire the Czechs, especially as they have elected a sensible politician with the aim of abolishing the global warming religion in the European Union, which are under the Czech Republic presidency in 2009.
