Since 1987 the Sky brightness have been measured in the UCM Observatory through analog photometers. As the UCM Observatory it is located inside Madrid city, It is a perfect place to study the light pollution effects.The most important source of light pollution, came from the lamps inside its own campus.

 With the help of the local amateur association (ASAAF-UCM), we have made inventories of lamps and measurements inside the campus. This is the photo gallery.

Some work of the Students about the Light pollution on the campus (in Spanish):
