The 5th Annual GLOBE at Night Campaign is ready to begin!

GLOBE at Night is an annual 2-week campaign in March that helps to address the light pollution issue locally as well as globally.

Please read the latest GLOBE star regarding this campaign and mark your calendars to participate March 3th through 16th, 2010.

The observations times are 8 PM to 10 PM your local time and 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. We request that you submit your measurements on-line at http://www.globeatnight.org/report.html with your date, time and location. A few weeks later, organizers will release a map of light-pollution levels worldwide. Over the last four years, during these 2-week-long GLOBE at Night campaigns, volunteers from over 100 nations have contributed 35,000 measurements.

To learn about the five easy steps to participate in the GLOBE at Night program, see the GLOBE at Night website at:  http://www.globeatnight.org. You can listen to our 10-minute audio podcast on light pollution and GLOBE at Night at:  http://365daysofastronomy.org/2010/02/03/february-3rd-the-globe-at-night-campaign-our-light-or-starlight/

For activities to invite children to explore what light pollution is, what its effects are on wildlife and how to prepare for participation in the GLOBE at Night campaign, see the new activities at http://www.darkskiesawareness.org/DarkSkiesRangers.

Monitoring our environment will allow us as citizen-scientists to identify and preserve the dark sky oases in cities and locate areas where light pollution is increasing. All it takes is a few minutes during the March 2010 campaign to measure sky brightness and contribute those observations on-line. Help us exceed the 15,000 observations contributed last year. Your measurements will make a world of difference.
