Thames Valley at Night
The crew of the International Space Station acquired this image shortly after 7:22 p.m. local time on the evening of February 4, 2003. Either thin, low clouds or perhaps fog is evident in the fuzzy character of patterns for some of the surrounding smaller cities while that of the warmer urban center is still clear and sharp. The full image can be downloaded at the NASA image gallery.
