GLOBE at Night encourages citizen-scientists worldwide to record the brightness
of the night sky. During 2 winter/spring weeks of moonless evenings, children
and adults match the appearance of a constellation (Orion in February/March and
Leo and Crux in March/April) with 7 star charts of progressively fainter stars

The GLOBE at Night 2011 campaign dates are February 21 – 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!

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 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

  1. It is important to spread the message about this event and to participate in it yourself.

    The data collected will become valuable but the awareness is just as important.

    Light Pollution is everyone’s problem. Lets get control of it.
