Recently a new method has been developed to study the subsurface structure of sunspots, called 2-skip time-distance helioseismology (see Figure). Theoretically this is a useful method as it can separate thermal effects from magnetic effects. Observationally large signals are observed, as much as three minutes of travel time difference from a similar quiet-sun area. Significant signals from the outflows around the spot are also observed. What is needed are significant modeling efforts to show us what these observations really mean.
