This was taken at an old windmill on the South Downs north of Chichester. It looks more derelict than usual because 3 of the sails have been taken down for renovation. There was light from Chichester 2 miles behind me and Bognor Regis 8 miles to the South. These lit up the clouds to the north which I think adds to the picture. There was also a little sky glow from London 60 miles due north.
