Further to my #21, here are images of data as the eclipse passed over.
I quickly edited some explanatory text boxes over the images
The first one is from the power datalogger for my solar battery powered ham station.
It is as expected, the solar panels shut down completely and sharply at UTC19:15 confirming the estimated alignment time in local media here.

The re-combination and re-ionization are clearly shown, I think.

Queries ??
-If the signal was a symmetrical hop, the doppler shifts would have been at a position halfway between my QTH and CHU,
which is a bit North of Toronto and later in time.
-If the signal was a Pederson mechanism, there would have been two doppler shifts at different times.
-So maybe this signal was an asymmetrical NVIS ( near vertical incident skywave.) ??
There are about 60 hams contributing data , so the researchers report will be interesting.
