GLOBE at Night 2009GLOBE at Night - Home page: "Once again, the GLOBE community is invited to participate in the annual global sky observation known as GLOBE at Night. GLOBE at Night brings people outside to observe the constellation Orion from 16-28 March 2009. Participants simply choose a clear night on which stars are visible, take measurements of stars in this portion of the sky using GLOBE's Magnitude Charts, and enter observations into the GLOBE at Night Web site. Students — alongside teachers, parents and community members-- amass a data set from which they can begin to explore the concept of light pollution and to research the patterns of light pollution across the globe.
16 - 28 March
Participation in GLOBE at Night is open to anyone who lives or works in one of the 110 GLOBE countries and can get outside and look skyward during 16-28 March. You can enter your observations on the GLOBE at Night Report web page from 16 March - 7 April."
