Greetings, fellow astrophiles!
With thanks to George Normandin of the Kopernik Astronomical Society (and Art Cacciola for emphasizing the importance of getting this PDF distributed), we’re making mention here of the publication of a fairly recent (April, 2018) International Astronomical Union (IAU) report on Light Pollution.
The direct link and additional details are below.
As a more recent point of note, the recommendations of amber/yellow colors for “ecologically responsible and astronomically friendly LEDs” is a relevant extension to a June 2016 article in Sky and Telescope titled “Is Red Light Really Best?” where author Robert Dick presented quite compelling arguments for shifting your nighttime observing lights a bit towards amber.
2018 Light Pollution Brochure – Download
From the IAU website:
This publication is a compilation of important findings of experts worldwide in the area of light pollution. The information was gathered under the umbrella of the Cosmic Light programme, organized by IAU during the International Year of Light 2015. The goal of this brochure is to raise the profile of recent advancements in our understanding of light pollution, in particular regarding the use of LEDs, to support the astronomy community and increase public awareness of light pollution research.
You can download this brochure as a high resolution pdf or as a medium resolution pdf.
