Light pollution
Light pollution is the level of radiance (night lights) shining up into the night sky. The Campaign to Protect Rural England (CPRE) divides the level of night sky brightness into 9 bands with band 1 being the darkest i.e. with the lowest level of light pollution and band 9 the brightest and most polluted. Roxton in band 5 and 6 is adversely affected by lighting along the A1/A421 Black Cat Roundabout. The night sky is darker looking northwest.
