Greenland

Last evening, I could see that the geomagnetic field was moderately disturbed, so I kept the 20m delta listening on WSPR all night long.

There were no unusual spots received here or spots of my signal overnight, but once again, G0CCL's signal, from just a couple of hundred km away, proved sensitive to the geomagnetic field.

The disturbance was picked up most clearly by magentometers in western Greenland. here showing the Z (vertical) component:


And here is how G0CCL's signal responded, suddenly reappearing out of the noise and into a fairly strong signal (grey area) as the field shifted:
