Motions in the sun reveal inner workings of sunspot cycle

We should study the sun more.  I am happy that some of us, like them,

do study it more thoroughly.  I was not aware that you could study the sun using sound waves (helioseismology) to study the sun.

At the beginning of a solar cycle, sunspots emerge at mid-latitudes. As the cycle progresses, they emerge closer and closer to the equator. To explain this “butterfly diagram,” solar physicists suspect that the deep magnetic field is carried toward the equator by a large-scale flow.
