GLOBE at Night is an annual March program designed to highlight the effects of global light-pollution.
As noted on the GaN website, people from all over the world record the brightness of the night sky by matching its appearance toward the constellation Orion with star maps of progressively fainter stars. They submit their measurements on-line and a few weeks later, organizers release a map of light-pollution levels worldwide. Over the last four GLOBE at Night campaigns, volunteers from over 100 nations have contributed 35,000 measurements. What a great use of the Web to engage a group of citizen-scientists in a project!
You can participate by clicking over to the GLOBE at Night website to download free materials and instructions. This year's program runs from March 3rd through the 16th.
