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.
