Abstract SOHO offers an unprecedented opportunity to probe the interior of a star with the techniques of helioseismology. Continuous distortion-free observations of the Sun will provide unique measurements of its internal structure and dynamics. The MDI instrument provides the capability to obtain observations with very high spatial resolution and high precision at all times, with statistical errors well below the expected solar noise background at all frequencies. The real limitation will be gaining a sufficient understanding of the systematic error sources with characteristic periods longer than several hours.
