Inter-Division B-C Commission WG Technical Working Group


The Technical Working Group has the major objectives to:

  • Provide technical specifications at engineering levels for standards for outdoor lighting that promote dark sky protection.
  • Inform the broader professional astronomy community about the technical issues of radio-frequency interference and mitigation efforts.
  • Provide data and access to modeling that maps artificial sky glow by region and over time and that could provide the basis for assessing impact of new installations.
  • Provide measurements and other data on the impact of enhanced airborne dust from mining, construction and other activities in proximity to major observatories, to provide the basis for voluntary and regulatory controls.
  • Provide a forum for astronomer efforts to enhance local and national legal frameworks for general dark sky protection in the context of the IAU Right to Starlight initiative.


Aspects of Implementation:

  • Close interaction with CIE to set illumination standards that protect astronomical observations.
  • Encouragement of industry efforts to produce spectrally controlled LEDs.
  • Close interaction with International Dark-Sky Association.
  • Establishing and reinforcing links with other scientific communities also affected by light pollution, especially from the fields of Biology and Human Health.
