Splitting of the Sun's global oscillation frequencies by large-scale ows can be used to investigate how rotation varies with radius and latitude within the solar interior. The nearly uninterrupted observations by GONG yield oscillation power spectra with high duty cycle and signal-to-noise ratio. Frequency split-tings derived from GONG...

The solar magnetism is no more considered as a purely superficial phenomenon. The SoHO community has shown that the length of the solar cycle depends on the transition region between radiation and convection. Nevertheless, the internal solar (stellar) magnetism stays poorly known. Starting in 2008, the American instrument HMI/SDO and the...
