The usual story is that after a solar flair (coronal mass ejection) towards the earth the earth's magnetic field gets strongly deformed. It usually takes a few days from the solar event to when the earth is impacted. But I wonder if there is also a direct interaction: If there is drastic change of magnetic activity in connection with a large solar spot, should this not affect directly the earth's magnetic field? The change of these fields should propagate at light speed, so we should have some effect on the geomagnetic field 8 minutes later, and then if there is a major increase of solar wind, another and different impact 2-4 days later. Question is: Compared to the impact of solar wind, Is that first effect too small to actually matter or is it significant? And how could it be measured.
