Abstract: We compare helioseismic maps of large active regions on the far side of the Sun, calculated from Global Oscillation Network Group (GONG) data, with magnetic and visible-continuum images of the same active regions on the visible hemisphere before and after their passage across the far hemisphere. We find a significant correlation between the far-side signature and both the total area of the active region as viewed on the near hemisphere and the total area of sunspots within the active region. We have also studied the relationship between the magnetic field strength and the phase shift for six of the larger, more stable active regions.
