Global Oscillation Network Group (GONG) H-alpha Outputs (oHA)

Metadata Updated: May 5, 2023

Originally constructed in 1995, the Global Oscillation Network Group (GONG) is a network of six identical ground-based solar telescopes distributed around the Earth in order to obtain continuous observations of the Sun. Those sites are located in Big Bear, California (BB); Mauna Loa, Hawaii (ML); Learmonth, Australia (LE); Udaipur, India (UD); El Teide, Spain (TD); and Cerro Tololo, Chile (CT). Additionally, there are three engineering/testbed sites in Boulder, Colorado (TC, TE, and TS). Owned by the National Science Foundation, GONG is operated and maintained by the National Solar Observatory (NSO) with significant funding from NOAA’s Space Weather Prediction Center (SWPC). Each minute, weather permitting, the GONG network observes the Sun at two spectral wavelengths: 676.78nm (a Ni I absorption line) and 656.28nm (the H-alpha absorption line).
