Join the Worldwide GLOBE at Night 2012 Campaign

GLOBE at Night is a worldwide, hands-on science and education program for primary and secondary schools. The GLOBE at Night project encourages citizen-scientists worldwide to record the brightness of the night sky. During four select sets of dates, children and adults match the appearance of a constellation (Orion or Leo in the northern hemisphere, and Orion and Crux in the southern hemisphere) with seven star charts of progressively fainter stars. The map is located at http://www.globeatnight.org. Participants then submit their choice of star chart online with their date, time and location to help create a light-pollution map worldwide.

The GLOBE at Night 2012 campaign dates are Feb. 12-21, March 13-22 and April 11-20, 2012. Over 68,000 measurements have been contributed from more than 115 countries over the last six years of two-week campaigns.

Children and adults can submit their measurements in real time if they have a smart phone or tablet. To do this, use the Web application at http://www.globeatnight.org/webapp/. With smart phones and tablets, the location, date and time are put in automatically. And if you do not have a smart phone or tablet, there are user-friendly tools on the GLOBE at Night report page to find latitude and longitude.

Through GLOBE at Night, students, teachers, parents and community members are amassing a data set from which they can explore the nature of light pollution locally and across the globe. Make a difference and join the GLOBE at Night efforts in 2012. Activity packets, one-page flyers and postcards advertising the campaign are available at http://www.globeatnight.org.
