AB: A correlation analysis between the interplanetary electric field and the magnetograms recorded at Godhavn (Qeqertarsuaq), a polar cap geomagnetic observatory, is performed. A direction, along which the latitudinal dependence of the geomagnetic perturbation is minimum, is found, and allows us to apply the correlation results to pre-satelitte data, back to 1926. The findings indicate no secular trend in the cross-polar cap electric field, in the interplanetary electric field, and by inference in the sun's open magnetic flux, since 1926. The result is independent of the aa geomagnetic index.
