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 full view of the sun at the start of the fly-in.
