NSO is actively blocking SOL24.net from accessing publicly available GONG data. Alternative data retrieval methods are in place – this leads to delays and potential data gaps.

The Global Oscillation Network Group (GONG) is a community-based program to conduct a detailed study of solar internal structure and dynamics using helioseismology. In order to exploit this new technique, GONG has developed a six-station network of extremely sensitive, and stable velocity imagers located around the Earth to obtain nearly continuous observations of the Sun’s “five-minute” oscillations, or pulsations. You can check the stations’ locations here.
