Hi Rik,

...
I am not sure thatthe morningdip is relatedto the eclips,
the propagation path didn'tcross the eclips line at anytime.
...

There's no need that the signal of interest must cross
the eclipse line. The ionosphere height is influenced
over all paths where the eclipse can be seen. How strong
this influences signals depends mainly on the phase
difference between ground and sky wave or between the
phases from multiple hop propagation. HGA22 is at 1000km
of distance from here. That's nearly optimal for this
interferometric effects on LF.

Looking at the
graphs, knowing therewas an eclpis but not knowing when itwas, mybest gues 
would be14h15.
...

Please compare both plots from yesterday and today.
There's a clear "W-shape" observable in magnitude around
0945 ut.
