protected for all-weather use.OpticallightmeterLightmeter Data We give continuous night and day light measurements at all natural
outdoor light levels by a network of low-cost lightmeters. Developed
to start simple, global continuous high cadence monitoring of night
sky brightness and artificial night sky brightening (light pollution)
in 2009. The lightmeter network is a project of the Thüringer
Landessternwarte, Tautenburg, Germany and the Kuffner-Sternwarte
society at the Kuffner-Observatory, Vienna, Austria.
It started as part of the Dark Skies Awareness cornerstone of the
International Year of Astronomy.
