光害
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.
