About SOI

The Solar Oscillations Investigation is an international project to study the interior structure and dynamics of the Sun. The SOI program was responsible for design and fabrication, and now for operation, of the Michelson Doppler Imager (MDI) instrument on board the Solar and Heliospheric Observatory (SOHO) spacecraft, launched on December 2, 1995. The SOI Science Team includes over 60 scientists from around the world.

In addition, SOI is building an archive of helioseismology data from several other solar projects.
