GLOBE at Night 2011

3 December 2010

GLOBE at Night encourages citizen-scientists worldwide to record the brightness of the night sky. During 2 winter/spring weeks of moonless evenings, children & adults match the appearance of a constellation (Orion in February/March and Leo in March/April) with 7 star maps of progressively fainter stars found at www.globeatnight.org. They then submit their choice of star map on-line with their date, time and location to help create a light pollution map worldwide.

The GLOBE at Night 2011 campaign dates are February 26 – March 6 (worldwide) and March 22 – April 4 (for the Northern Hemisphere) and March 24 – April 6 (for the Southern Hemisphere). 52,000 measurements have been contributed from more than 100 countries over the last 5 years of two-week campaigns, thanks to everyone who participated!

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. Please make a difference and join our efforts in 2011. For one-page flyers and postcards advertising the campaign, visit www.globeatnight.org/pdf/.
