3-4 weeks either side of the winter solstice, I worked a dozen or so EU stations using FT8. Nearly all were on the daylight side of their sunrise. Best DX was a UA7 in Zone 17! Last weekend in ARRL DX CW, I worked a bunch of EU stations on 80M, most well into daylight after their sunrise. 73

Isn't the auroral zone centered on the "geomagnetic pole" rather than the "magnetic pole"? Given that the geomagnetic pole is hardly moving at all in comparison with the magnetic pole, that would indicate that the location of the auroral zone itself shouldn't have moved too much since the las

Thanks for the comments in this discussion. I have in previous posts commented on the magnetic north pole and it's migration towards Siberia. I feel this has been the primary cause of propagation disturbance at my location. That and I'm at the wrong distance from the aurora itself creating the

Dave, Thanks for your reply. I am reminded that here I may have topographic maps from late 1800's possibly and from the late 1950's. I will dig them out to see what they show. I assume the numbers you show are for London. Also I'd expect to find accurate current values for my location on line

Years ago, I think the correction was more like 17 degrees in New England.  I did some work on the geomagnetic field some years ago, and remembered getting magnetic variations for London, England over the last few  centuries. The pole really does move. YEAR   DECL. 1600  8E 1650  1E 1700  7W

Hello Frantisek and others, I wonder how much the magnetic pole has shifted. I have been reviewing the operation of the Brunton Pocket Transit here. It has an adjustment for declination - the angular difference between the magnetic North Pole and the true rotational axis North Pole. Here in

Hey Bob, I found the season typical though signals in general were down from this part of the cycle. I did work 128 European stations in the CQ 160 which is a personal best for me. There were many nights when I had the EU RBN lit up with huge reports but no answers to many CQ's. I blame that on
