Globe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations. It's easy to get involved - all you need is computer or smart phone & follow these 6 Simple Steps!
To find Bootes, look for the Big Dipper constellation in the north. Follow the arc made by the Dipper's handle until you see a bright star. This is Arcturus, which is located in what would be the waist of Bootes. The rest of the stars in Bootes form the shape of a kite, with dimmer stars beneath the diamond shape of the kite forming his legs.
