With helioseismology we can see that an active region is on the sun’s far side, the side facing away from Earth. The dark patches on the far-side images (absent when no significant active regions are on the far side) indicate the presence of active regions. Right at the left limb of the Sun (orange/dark areas) we see a dark large active region AR13133. The magnetic map of the Sun is shown in grey/yellow.

The full story is at the JSOC html site and a general description of the rattling Sun is at EoS.org
