SOHO/MDI Investigates Solar Flows Under Sunspots

View full credits

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.

Just below the solar surface, we can display isosurfaces of temperature anomalies.  Blue is cooler than average, red is warmer than average, and yellow is just a little warmer than average.
