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.
What: The Globe at Night Campain
When: 8pm - 10pm local time, March 3-16, 2010
Where: Everywhere!
Who: You! (Everyone!)
How: see http://www.globeatnight.org
Why: 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 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 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.
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.
