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
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 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.
