Ham HF txcvrs (2)  are running here for the HamSci eclipse data collection.
One is measuring the doppler shift of the signal from time signal CHU Ottawa 7850 kHz. Measurement is by FLDIGI in FMT mode.
Receiver is GPSDO clocked  and set USB mode 1000Hz below CHU, so the base signal to FLDIGI is 1000Hz.

The path  CHU to here is almost parallel with and ~ 80 km north of totality edge.
Distance to here in mid Michigan is 687 km, so 1 hop.
After the sunrise transients the signal so far today is steady with no offset and occasional transients of about 200 milliHertz.
If there is a good trace as the shadow passes,  I will put it up in this thread.

Noooooooooooo...... The clouds are rolling in.  It's become hazy and thick overcast, though you can still see the sun through it, it will completely ruin the eclipse.

~35min to totality where I'm located...

No words required, it was quite a spectacle.

Joking aside, I am in Dallas and it was spectacular, even though there were some scattered clouds.
