SOHO/MDI Investigates Solar Flows Under Sunspots

SOHO/MDI performs a 'sonogram' of the sun, revealing the subsurface temperature profile around a sunspot. Red isosurfaces denote regions where the sound speed (and temperature) are higher than average while blue isosurfaces directly under the spot illustrate where the sound speed (and temperature) are lower than average.

A fly-in to the solar surface. The view dives below the surface to reveal temperature anomalies derived from helioseismology.
