This short path over or near the polar regions seems to be best during low 
sunspot years.  In fact 1997 was the best year propagation-wise around the last 
sunspot trough, at least from my perspective.  On the other hand, the sunrise 
long path seems to peak up in high sunspot years which obviously is now.

Back in the mid-1980's (around the sunspot minimum in that period), in W1 we 
would sometimes get propagation over the North Atlantic short path at our 
sunrise.  It was common to work Zone 40 this way.  I have not seen this path 
open here since that time, however.  In fact, that period in the 1980's 
produced extended periods of outstanding lowband propagation that hasn't been 
repeated since (at least not for me).
