I'e been scratching my head in trying to relate the Kiruna magnetometer output with changes in HF propagation.

...until you examine stations at higher latitudes.
It turns out that Kiruna is too far south, even at 67 degrees north, to reveal the changes relevant to HF in the auroral zone.
For a more reliable output in terms of effects on HF, one has to look at Nordkapp, which is at 71 degrees north. Or Tromso, at 69 degrees north. These stations typically show large variations in the magnetic field, when Kiruna shows almost a flat line.
So, if you are interested in high latitude WSPR, then have a look at multi-station stackplots like those available here, to ensure you have the best chance of understanding what's going on.

Those magnetometer plots are interesting. Do you know whether the raw data is available in a format that would allow me to plot my own graphs like I do for from ionogram data here https://jail0219.nowindows.net/radio/propo.php? 73,Nick.
There's no appaent link to raw data on the web page. May be worth contacting the institution(s) listed on that page to see whether they release raw data. Many do, given the public ususally pay for its generation!
