A recent example of light pollution in the Eastern USA
Defense Meteorological Satellite Program satellite F16, Earth orbit
Nov. 10
from Mark Conner of the Meteorological Satellite Applications Branch, Air Force Weather Agency:
"This is a mosaic of DMSP F16 data for the evening of 9 November (10 Nov between 00 and 04 UTC) over North America, showing the auroral extent at that time. The light wispy bands and swirls are the aurorae. There is enough moonlight available to show some cloud details, and the city lights shine brightly in clear areas."
