Global Oscillation Network Group (GONG)




A network of six observatories around the world that provides almost continuous, highly sensitive monitoring of the Sun's pulsations. The data collected is used for detailed studies of solar internal structure and dynamics (see helioseismology). GONG began operation in 1995, is managed by the National Solar Observatory, and involves sites in the Canary Islands (Teide Observatory), Western Australia (Learmonth Solar Observatory), California (Big Bear Solar Observatory), Hawaii (Mauna Loa Solar Observatory), India (Udaipur Solar Observatory), and Chile (Cerro Tololo Inter-American Observatory).
