Temperature and Flows under a Sunspot (Layers 0, 2, 4)
Using the SOHO Michelson Doppler Interferometer (MDI), scientists can use a process called Time-Distance helioseismology to determine temperatures and fluid flows under the surface of the Sun.
Zoom into the sunspot and reveal temperature and flow profiles revealed by time-distance helioseismology.
Temperature anomalies (color) and flow directions at the solar surface. The darker blue region corresponds to the sunspot itself.
Layer 5000 kilometers below the solar surface.
Layer 9000 kilometers below the solar surface.
Video slate image reads "Temperature and Flows under a Sunspot (Layers 0, 2, 4)".
