Helioseismology
The modern field is separated into global helioseismology, which studies the Sun's resonant modes directly, and local helioseismology, which studies the Local helioseismology
Local helioseismology—a term coined by Charles Lindsey, Doug Braun and Stuart Jefferies in 1993—employs several different analysis

Scientific Rationale
Since the beginnings of global helioseismology in the late 1970s, the detection of g modes has been the quest for the Grail. Aboard SOHO, there are three instruments dedicated to helioseismology all aiming at detecting g modes.

GONG was constructed to provide observations for helioseismology, which aims to understand the solar interior by analyzing the sound waves that are trapped While GONG still provides helioseismology data, it now also provides full-disk solar magnetic field maps (magnetograms) every minute and full-disk images
