Isn't the auroral zone centered on the "geomagnetic pole" rather than
the "magnetic pole"? Given that the geomagnetic pole is hardly
moving at all in comparison with the magnetic pole, that would
indicate that the location of the auroral zone itself shouldn't have
moved too much since the last solar minimum.

Thanks for the comments in this discussion.
I have in previous posts commented on the magnetic north pole and
it's migration towards Siberia. I feel this has been the primary
cause of propagation disturbance at my location. That and I'm at the
wrong distance from the aurora itself creating the high absorption.
Here are a couple of links to visualize what I perceive is the
cause. Fortunately 160m is almost always open somewhere after dark,
not necessarily where I want it to be.
Yesterday I worked EA7X two hours after sunset and then the band closed.

On the NOAA page click on the right hand image of the Aurora and run
the 24 hour collection. You can see I'm in the wrong place at the wrong time.
