Direct and indirect light pollution around Madrid

This map shows the zenith sky brightness around Madrid in Spain, based on ISS images. The white areas indicate direct light from streetlights and the diffuse light component corresponds to other colours, confirmed from the ground. The units are magnitudes/arcsec2.

The image was taken by Alexander Gerst with European Space Agency’s NightPod device which compensates for the station’s speed and the motion of the Earth below.
