"We aim to compare the polar coronal
hole boundaries with the averaged magnetic field spatial distribution to determine if
there is any tilt in the global dipole field with respect to the Sun’s equator. In Chapter 7
we showed that there is an apparent wobble in the 5G contour of the ⟨B+⟩ butterfly
map, alluding to an offset in the magnetic axis to the rotational axis of the Sun. The
inclination of the axes would wobble back and forth, and hence the boundary of the
polar field, from the perspective of the Earth. This has important implications, since
it implies that the magnetic dynamo is not azimuthally symmetric and that we must
abandon our classical view (Parker, 1955a) of magnetic field generation. The size of the
temporarily stable (at solar minimum) polar field configuration also has implications
for magnetic surface diffusion."
