Sunspots are darker regions which often appear on the Sun's surface. They are caused by strong concentrations of magnetic field, and can be as big as the Earth, or even much bigger.

From the end of the 1960's the presence of oscillations in the atmospheres of these spots has been known, and interpreted as evidence for magnetic waves.

These waves have attracted the interest of the researchers, because they could transport energy from the interior layers of the Sun up to the outer regions of the solar atmosphere.

NASA's Solar Dynamics Observatory watched AR26665, an active region -- an area of intense and complex magnetic fields -- rotate into view on the sun.
