It's that time again... time to get outside, check out the sky for a few minutes and make a contribution to preserving dark skies. Time for GLOBE at Night. If you didn't see my posts in 2009 or 2010, read on.
GLOBE at Night is a citizen-science campaign open to people all over the world to raise awareness of the impact of light pollution by inviting citizen-scientists to measure their night sky brightness and report their observations to a website from a computer or smart phone. Light pollution threatens not only our “right to starlight”, but can affect energy consumption, wildlife and health. Through 2011, people in 115 countries contributed 66,000 measurements, making GLOBE at Night one of the most successful light pollution awareness campaigns to date. This year, the campaign takes place over 4 weeks:
- January 14 through 23
- February 12 through 21
- March 13 through 22
- April 11 through 20
