CPRE star count results


Recommended Posts

I had an email newsletter from the Campaign to Protect Rural England today - amongst other things, revealing the findings of the star count event they promoted in early 2011.

I took part in this, as many others on this forum did - by counting the amount of stars that can be seen within the constellation Orion.

Their results reveal that in just four years, light pollution has got worse.

Whilst I am obviously unhappy with the results, part of me does wonder about the accuracy of such a test...as it seems as if more people took part in the 2011 survey compared to the 2007 one.

I think there's a market for luminescent concrete / tarmac / similar to use on pavements.

Now I've typed it, it doesn't sound that stupid... This counts a prior art, btw, though I'm not sure if SGL or I own it!

luminescent, not fluorescent, obviously :)

The trouble is Sam, there are soooo many factors involved in a dark sky that it would be almost impossible to guarantee a useful result with such a method.

Every year at Kelling SP you hear it said "The light pollution is a lot worse this year"

I guess if there was a reading taken daily and then averaged, and then that compared to the previous year you light get a half useful result.
