Ed N4II published a compelling explanation in the November/December issue of
QST: "Gray Line Propagation, or Florida to Cocos
(Keeling) on 80m". The article is available here
<http://www.arrl.org/files/file/QEX%20Binaries/2016/Callaway.pdf>
and a presentation is available here:

Subject: Topband: DX Propagation long path is getting strong this season
Hi topband lovers
Comments and an heads-up to watch for openings SSE/SSW on 160, 80, and 40m.
This DX season is starting somehow different from last ones. Two weeks ago a
heard BD7PUZ 569 for 15 minutes after my SR (22:30z) on
160m, signal coming
150 degree SSE. It was the first time I heard China on 160m in the evening.
The DSt index is unprecedented high near +20 for few days. DSt will plunge
again soon when we get hit by the arriving G1 magnetic
storm coming. DSt needs to be above +0 for several days for good possibility of
long path,

This morning WL7E signal was stronger long path 210 degree, also it was the
first time I heard KL7 from 210 degree. Joe signal was
579, real a strong signal ( horizontal polarized) , N4II also using a Waller
Flag heard the same from the Boca Ratoon DX Club.. Joe
mentioned that he worked several Europeans last week pointing antenna toward
Australia, near 210 degree, again the same SSW/SSE
path.
I can say for sure it is difficult to understand why SSW/SSE direction for
almost everywhere you are in the north part planet. PY2RO
is using a Waller Flag and now he tell us how direction long path is arriving
for stations south of the equator.
December 2011 was the best long path propagation day I remember. It seems that
conditions is coming back. I hope more good long
conditions is possible this DX season. JA7QVI Tac also worked long path this
morning but some QSB and a quick shift towards west.
Joe (WL7E) also reported poor condx to Japan this morning, go figure!
We don't understand it ,but enjoy it for sure, Any comments on SSE/SSW are
welcome , this propagation mode is becoming more common.
