Topband: 160m activity and propagation

[W7RH]

The emphasis of my questions are based on European propagation path 
perceived differences since last solar minimum.

One thing I am not is a Geophysicist, I have no training there. My 
comments are on perceived changes in the aurora ring density as viewed 
from my location in Arizona that would have been in the past much lower 
on the path towards Europe far more often than present. I'll call it 
prime time wipe out. Very small changes in solar wind have had a 
profound effect. Whether the center point is the magnetic north pole or 
the Geomagnetic pole I have no idea as both have migrated with the 
Magnetic North pole the greatest at a rate of 30 miles per year and 
increasing.

Perhaps the reduction of magnetic field over North America and increased 
gamma radiation create the effect. In a related article it stated the 
magnetic field over North America is 15% less than it was in 2015.

Trying to get a better grasp of what is going on.
