Globe @ Night


March 16-28, 2009

Globe At Night

As an original member of the Share the Skies VDOE State Initiative, Ms. Marshall was designated as state coordinator for the International GLOBE at Night Project. With 2009 being the International Year of Astronomy, and Share the Skies such a great success, the opportunity presented itself for Virginia to be involved in an International Project: GLOBE at Night.

The classic GLOBE at Night program directs students, families, and the general public how to observe and record the number of stars visible in the constellation Orion, as seen from different locations. Observers report their results online by comparing their view of Orion with a set of template images on the program’s Web site, which shows the number of stars in the constellation for a range of visibilities from bright skies to very dark.

The digital version of GLOBE at Night takes advantage of low-cost digital SQMs (Sky Quality Meters) manufactured by Unihedron of Ontario, Canada, which can make a highly repeatable direct measurement of integrated sky brightness.

Both the “classic” GLOBE at Night exercise that anyone can have fun doing with their unaided eyes, and a digital effort to obtain precise measurements of urban dark skies will be conducted March 16-28 2009, as one of several start-hunting efforts connected to the “dark-skies awareness” cornerstone program of the International Year of Astronomy (IYA) 2009.

GLOBE at Night is a collaboration between The Global Learning and Observations to Benefit the Environment (GLOBE) Program, Boulder, CO; the National Optical Astronomy Observatory (NOAO) in Tucson, AZ; Centro de Apoyo a la Didactica de la Astronomia (CADIAS) in Chile; Environmental Systems Research Institute, Inc. (ESRI); and the International Dark-Sky Association (IDA).

GLOBE (Global Learning and Observations to Benefit the Environment) is a worldwide, hands-on, primary and secondary Earth science and education program. GLOBE promotes and supports student-teacher-scientist collaborations on inquiry-based investigations of Earth’s environment. To date, over 1 million students and 40,000 teachers from more than 100 countries have participated in GLOBE. GLOBE is funded by the National Aeronautics and Space Administration (NASA), supported by the National Science Foundation (NSF) and the U.S. Department of State, and implemented through a cooperative agreement between NASA, the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado and Colorado State University in Fort Collins, Colorado.
