DID YOU KNOW THAT THE SUN'S POLES SWITCH OVER EVERY 11 YEARS? | Robin Monotti Cory Morningstar

DID YOU KNOW THAT THE SUN'S POLES SWITCH OVER EVERY 11 YEARS? LAST FLIP IN 2013, NEXT IS NEXT YEAR:
They do so "every 11 years at the peak of the solar activity cycle. While solar physicists know enough about this strange phenomenon to predict when it will occur, its ultimate causes remain mysterious.

"That gets into the whole [solar] cycle, and wondering what that is," Stanford University solar physicist Phil Scherrer told SPACE.com. "We still don't have a really self-consistent mathematical description of what's happening. And until you can model it, you don't really understand it — it's hard to really understand it."

During the field flip, the sun's polar magnetic fields will weaken all the way down to zero, then bounce back with the opposite polarity. The shift is closely tied to the activity of sunspots (also known as active regions), said fellow Stanford solar physicist Todd Hoeksema, who runs the university's Wilcox Observatory.

"The magnetic field from active regions makes its way toward the poles and eventually causes the reversal," Hoeksema told SPACE.com."
