GLOBE AT NIGHT CAMPAIGN

(March 3-16; 8:00-10:00 p.m. local time)

Globe at Night is an annual 2-week campaign in March that helps to address the light pollution issue locally as well as globally. This year the campaign is March 3-16, 2010. You are invited along with everyone all over the world to record the brightness of your night sky by matching its appearance toward the constellation Orion with star maps of progressively fainter stars found at http://www.globeatnight.org/observe_magnitude.html

You then submit your measurements on-line at http://www.globeatnight.org/report.html with your date, time and location. A few weeks later, organizers release a map of light-pollution levels worldwide. Over the last four 2-week Globe at Night campaigns, volunteers from over 100 nations have contributed 35,000 measurements.

To learn the five easy steps to participate in the Globe at Night program, see the Globe at Night Web site at http://www.globeatnight.org.
