The SOHO Mission and Helioseismology
Abstract
Three of the SOHO scientific instruments are devoted to helioseismology, and the mission has been designed with specifications that are required to obtain good oscillations measurements. The three instruments were selected to complement each other to achieve a comprehensive set of data to tackle the pending helioseismologic problems that were considered difficult to solve with ground-based instruments. GOLF (l = 0-3) and VIRGO (l = 0-7) in the low degree modes area and MDI in the complete range up to l = 4000 modes. In addition, several instruments of SOHO investigate, by imaging and spectroscopy, the transition region and the corona. Three other investigations aboard SOHO study "in situ" the resulting solar wind and energetic particles.
