It appears our sun is about to flip poles. I was stunned to learn this happens every 11 years; or at least that seems to be the pattern since the Wilcox Solar Observatory at Stanford started paying attention in 1976. The sun’s magnetic influence is called the heliosphere, reaching outwards for billions of kilometres , directly impacting space weather in every corner of our galaxy.

The “current sheet” radiates outwards from the equator of the sun. Slow rotation of the sun’s magnetic field produces an electrical current, when the sun’s inner core tidies itself up, reorganizing the closets, a pole shift takes place making the current sheet “wavy”.
