SOLAR-EARTH magnetic link
For some time now I claimed that such link exists, but this is disputed by experts. Here I present, if not definitive then at least initial step towards the proof of existence of the imprint of the solar magnetic activity on the Earth's magnetic field.
Of particular interest is geomagnetic minor 'flip' in 1970s.
Up to that time the Hudson bay magnetic pole negative gradient was faithfully following, with minor exceptions, the solar activity with a (for the moment not explicable) 34 year delay. In 1970 this correlation changes sign.
