Sun Set To 'Flip Upside Down' Within Weeks:
"Todd Hoeksema, a scientist at Stanford University's Wilcox Solar Observatory, said the polar reversal takes place as the Sun's magnetic field moves north or south from the equator, eroding the existing pole as it does so.
"It's kind of like a tide coming in or going out," he said. "Each little wave brings a little more water in, and eventually you get to the full reversal."
Latest measurements show the Sun technically has two south poles, caused by its two hemispheres being out of sync.
Phil Scherrer, who works with Mr Hoeksema at the observatory, said: "The north pole has already changed sign, while the south pole is racing to catch up.
"Soon, however, both poles will be reversed, and the second half of solar max will be under way.""
