Please post, promote or participate in the worldwide light pollution  
monitoring campaign, GLOBE at Night, happening now....(Thank-you.)

-------------------------

More stars. Less light. Participate in GLOBE at Night!

Calling all Earthlings! Take a few minutes to get involved in the  
GLOBE at Night campaign to preserve dark skies! 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.  
Please join us to participate in the 2012 campaign an hour after  
sunset til about 10pm January 14 through 23, February 12 through 21,  
March 13 through 22, and April 11 through 20. For information and  
resources, visit us at www.globeatnight.org.
