Lightmeter detection of the Aurora in northern Germany seen by many observers on 2015-03-18. A proxy for the horizontal illuminance is show as function of time [UTC]. The red and blue curves are for the two lightmeters with a raw calibration. The entire night is shown in the range below 3 mlx. The Auroral signal is visible as a triangular bump near 23:00 UTC. Graph: G. Wuchterl
The March 2015 fireball recorded by the Tautenburg Lightmeters, 2015-03-15, G. Wuchterl.
Nighttime total radiation at the Kepler observatory in Linz (Austria) measured under the exceptionally cloudy conditions from January to July 2013 - most overcast nights since the beginning of the records.
Comparison of the clear moonless sky medians of total radiation (divide numbers by 10 for a proxy of horizontal illuminance) measured in 2012 and 2013 by the stations of the Vienna Lightmeter Network.
Light-levels measured at the Setagaya/Tokyo Lightmeter station. Distribution of the night-time total radiation in 2012 at Setagaya Read the article Long-term Measurement of the Night Sky Brightness in Japan Using Lightmeters: 2009-2012 Data: [http://id.nii.ac.jp/1060/00006365/

The Lightmeter is a low cost instrument for global continuous monitoring of artificial night sky brightening (light pollution). The first version was developed for the International Year of Astronomy 2009.
