The Light Pollution: Theory, Modelling and Measurements Conference took place this year in Zselic Valley, Hungary, from 25 to 28 June 2019.
This meeting is held every two years and gathers researchers working in Theory, Modelling or Measurements of Light Pollution. The meeting focused on recent advances in scientific investigations on light pollution and its impact on astronomical observations. There were the usual talks and poster sessions and also plenty of time to discuss the topic selected: color changing world. The lights used to illuminate our streets are being changed from the warm orange sodium lamps to white LEDs. Some of the research presented was designed to be carried on with the participation of citizens. UCM presented one of these citizen science projects: the STARS4ALL network of photometers that monitor the night sky brightness with the help of volunteers all around the world.
