GLOBE at Night encourages citizen-scientists worldwide to record the brightness of the night sky. During 2 weeks of moonless evenings, children and adults match the appearance of a constellation (Leo in the northern hemisphere and Crux or Leo in the southern hemisphere) with 7 star charts of progressively fainter stars found at www.globeatnight.org. They then submit their choice of star chart on-line with their date, time and location to help create a light pollution map worldwide.

The GLOBE at Night 2011 campaign dates are March 22 – April 4 (for the Northern Hemisphere) and March 24 – April 6 (for the Southern Hemisphere). Over 60,000 measurements have been contributed from more than 100 countries over the last 5 years of two-week campaigns, thanks to everyone who participated!

This year children and adults can submit their measurements in real time if they have a smart phone or tablet. To do this, you can use the web application at 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. Please make a difference and join our efforts in 2011. For activity packets, one-page flyers and postcards advertising the campaign, visit www.globeatnight.org/pdf/.
