The GLOBE at Night 2007 program has been built upon the success of the inaugural campaign in March 2006 when 4600 observations were submitted by citizen-scientists from 96 countries. Participation this year is up by 50 percent.
The international star-hunting event known as GLOBE at Night returned March 8-21, 2007 in two flavors: the classic GLOBE at Night activity incorporating unaided-eye observations toward Orion, and a new effort to obtain precise measurements of urban dark skies toward zenith using digital sky-brightness meters. Both flavors of the program were designed to heighten the awareness about the impact of artificial lighting on local environments, and the ongoing loss of a dark night sky as a natural resource for much of the world population.
To make possible the digital GLOBE at Night program, the NSF funded 135 low-cost, digital sky-quality meters (manufactured by Unihedron). Along with related materials developed by the National Optical Astronomy Observatory (NOAO), the meters were distributed to citizen-scientists in 21 U.S. states plus Washington DC, and in 5 other countries, including Chile, where NOAO has a major observatory. The citizen-scientists were selected from teachers, their students, astronomers at observatories, International Dark-Sky Association (IDA) members and staff from 19 science centers. For each meter, citizen-scientists were asked to make 30 measurements from different locations in their region. The data is being pooled for regional analysis.
The success of GLOBE at Night 2007 is a major step toward the International Year of Astronomy in 2009, when one goal is to make the digital data collection into a worldwide activity. In this presentation, we will outline the set-up for the digital part of the program, the outcome and the plans for the future.
GLOBE at Night is a collaboration between NOAO, the GLOBE Program, CADIAS, Windows to the Universe, ESRI and IDA.
