Periodically over decades up pop comments like TEC count high, T indices good, the es over Norfolk high today blah blah blah.
At the risk of adding to the non sensical comments by the self appointed gurus I will add my bit at least from my summer experience anyway.
Starting back in late November 1993 after hearing VK3AUI on aurally modulated back scatter from the South south west 195-200 degrees
was able to receive the VK0AQ beacon taken by mark VK5AVQ to Casey that year.
For the record had I not declined a posting to be co-shared with Mark to DAVIS BASE and causing a major disruption to the ANARE employement of CCTO process
Mark got reassigned to CASEY and rest is history

Two years later on discussions at SERG with Darin same deal, beacon and liason with CASEY
and more history

propagation attributed to SPREAD F.
Argue if you like ask Darin and view the Antarctic sounder charts.
Eric VK5LP and I observed Sth and central American TV in 1997 1998 1999 over south polar paths using our two locations to df the paths,
then cycle 24 got in the way and stuffed it up.
Then the early warning last summer by VK3ZAZ, VK3OER and VK5PJ.

I tried with Dale for years to work Chile
and some years onand finally got DALE in the log

I will debate anyone anytime as to how the signals reach Southern Australia.
1988?
1992?
199?
2001?
2019?
game on!
This will start a good debate or NOT
