Chairman, Michael Bruton was interviewed on the BBC Radio Cornwall morning programme on 1st February about the joint CPRE/British Astronomical Association ‘Star Count Week’ – and explained the issues of light pollution in rural areas.

Light pollution in the countryside is a growing problem and takes away that rural feel as well as affecting animal life and sleep patterns. The plan was to look at the night sky one evening in the week and providing it was clear to count the stars in the Orion Constellation – and to submit results on the CPRE website.  Counting 30 stars (no telescopes allowed) means zero light pollution and 10 or less means strong light pollution.  Light pollution has worsened even in Cornwall where the Lizard and Land’s End peninsulas and Bodmin Moor are probably the only areas with truly dark nights.

Even though the count is now over if you want to try out the exercise – Google Orion. You will see the three bright stars on your PC (Orion’s Belt) and the belt is boxed in by four bright stars – that is the Orion Constellation.  So on a clear dark night how many stars can you count.

Light pollution, like noise pollution is a statutory nuisance and if you suffer ring up your environmental health department (street lighting and airport lighting, etc, are excluded from this law).
