Resumen:

The Sun is a magnetic star, not as magnetic as some stars, or as it was when it was younger, but nonetheless magnetic fields dominate and even construct its atmosphere. There would be no corona without magnetic fields. The surface is also dappled with small scale magnetic field associated with surface convection cells, granules and supergranules. But sometimes we also see much larger and more powerful Active Regions containing sunspots. These are wounds in the surface of the Sun that allow waves and oscillations in the solar interior and atmosphere to be coupled much more directly than they usually are. In particular, they allow the Sun's internal seismology (the p-modes) to drive a variety of waves through the Active Region atmosphere, and conversely, the atmospheres to pollute the internal seismology. This makes active region helioseismology a very challenging field.
