  Title Measuring the Night Sky Brightness with the Lightmeter. Type Journal Article
  Year 2011 Publication ReVMexAA Abbreviated Journal  
  Volume 41 Issue Pages 46–49  
  Keywords Instrumentation; instrumentation: photometers; light pollution; methods: data analysis; methods: observational; site testing  
  Abstract We present a newly developed, low-cost photometer for long-term monitoring of the night sky brightness and

light pollution on Earth. The so-called Lightmeter is an as far as possible stand-alone operational, fully

weatherproof, and maintenance-free device. It provides a high data sampling rate of up to 1 Hz as well as a

superb sensitivity covering the whole brightness range down to the darkest night time conditions. The excellent

performance of the Lightmeter allows a continuously monitoring of the night sky brightness and opens a wide

range of applications at an observatory site like determining overall sky conditions in real time, cloud detection

and estimation of their velocity, measuring relative changes in extinction as well as the detection of long term

trends in brightness caused by an increase of artificial illumination. We will present first results of measurements

taken at Cerro Armazones, one of the best obser
