[Eratóstenes 2009] oin in the 5th Annual Globe at Night Campaign: 3-16 March 2010

[Beatriz Garcia]

presten atencion a este llamado.
Globe at Night es una de las actividades que la Union Astronomica sigue
propiciando y que desde hace 5 anios produce mapas mundiales del grado de
contaminacion luminica.
Los invito a bajar el material y a realizar la experiencia que es muy
sencilla .
Es cierto que debe hacerse de noche, pero si se organizan bien, es una
fiesta en cada escuela!

saludos a todos

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

*

*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.
