Hi Everyone,
Just got sent an interesting link to a website that is getting people to help create global light pollution maps.
http://www.globeatnight.org/
Looks interesting, you can include your own observations, plus they have past data there to browse.
From the site:
The GLOBE at Night program is an international citizen-science campaign to raise public awareness of the impact of light pollution by encouraging everyone everywhere to measure local levels of night sky brightness and contribute observations online to a world map. All it takes is a few minutes to participate between 8-10 pm, March 22 through April 6. Your measurements will make a world of difference.
