NSKY-CD: A System for Cloud Detection Based on Night Sky Brightness and Sky Temperature
Remote Sensing, 2023 Cloud cover is important meteorological information that still requires expensive equipment to be monitored from the ground, especially at night. The use of artificial lights at night causes light pollution, and clouds amplify this by reflecting light ...

The moon phases influence on the beginning of astronomical dawn determination in Yogyakarta
International Journal of Science and Applied Science: Conference Series, 2017 In astronomy, there are three types of dawn. They are astronomical, nautical, and civil dawn. The sunlight is starting to appear on the east horizon when the Sun altitude is 18o below the horizon. Hence, there is a change on the sky brightness.
