Additional note, I did this exercise for Abergavenny last week and although it was not the best of nights – it was a bit misty and very cold, I managed to count 14 stars in Orion from my back garden in Abergavenny. The app then informed me that that was better than 77% of places in the UK so that can’t be bad. – Nick Busby
Not sure if it will be clear at all this week but if it is there is an activity going on that the Campaign for Rural England organises each year. The idea is that you count all the stars you can see by eye in the constellation of Orion and send in the results. This will allow any changes to light pollution in the UK to be mapped.
