PLEASE POST IF POSSIBLE:

The 5th Annual Globe at Night Campaign: 3-16 March 2010

What: The Globe at Night Campaign

When: 8pm to 10pm local time, March 3-16, 2010 
Where: Everywhere
Who: You! (Everyone!)
How: See http://www.globeatnight.org<http://www.globeatnight.org/> 

Why:

With half of the world‚s population now living in cities, many urban dwellers 
have never experienced the wonderment of pristinely dark skies and maybe never 
will. This loss, caused by light pollution, is a concern on many fronts: 
safety, energy conservation, cost, health and effects on wildlife, as well as 
our ability to view the stars. Even though light pollution is a serious and 
growing global concern, it is one of the easiest environmental problems you can 
address on local levels. 

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 
athttp://www.globeatnight.org/observe_magnitude.html<http://www.globeatnight.org/observe_magnitude.html>.
 You then submit your measurements on-line at 
http://www.globeatnight.org/report.html<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 website at 
http://www.globeatnight.org<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/<http://365daysofastronomy.org/2010/02/03/february-3rd-the-globe-at-night-campaign-our-light-or-starlight/>

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