Quiest Sun May Be Cover For Activity Beneath the Surface

In a paper to be published in the Astrophysical Journal Letters, available online now here, a team of British astronomers address the concerns some have stated over the recent quiet Sun. Apparently, using the techniques of helioseismology, which like its namesake seismology, uses surface waves to determine what is happening beneath the surface, astronomers have discovered that there is evidence of quite a bit of activity just beneath the surface of the Sun or photosphere. Apparently there is “activity-related
processes occurring in the solar interior, which are yet to reach the surface.”
