In the previous minimum I could work North West USA and West Canada
almost every day.
Now it is rare.
The path to southwest USA and Carribean is better.

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.
