shifting at a rate of about one degree per year. That would take, about 180 years... not 'thousands of years'.
doesn't that read just blatantly wrong?

Re: Sunspot activity in freefall
I'm confused. I thought that the N/S Poles weakened and weakened and then, more or less, flipped. This makes it sound like half-way through the process one would see the North Pole as being a point on the equator - let's say, to the East (or what we used to call East).

I presume that it wanders a lot before flipping. Should've been explained; I did a double-take, too.Unagi wrote: ↑Wed Jul 08, 2020 11:53 pmIsgrimnur wrote: ↑Wed Jul 08, 2020 10:02 pmBut a few times every million years, the field's polarity reverses and the magnetic North Pole and South Pole trade places.

Re: Sunspot activity in freefall
So earth has a molten core that spins to create magnetic fields that protect us from cosmic rays. That seems pretty fortunate. Take that plus a large moon plus Jupiter that snatches up most asteroids and you've got some answers to Fermi's Paradox.

USA Today
A sunspot pointing toward Earth has the potential to cause solar flares, but experts told USA TODAY it's far from unusual and eased concerns over how flares would affect the Blue Planet.
Active Region 3038, or AR3038, has been growing over the past week, said Rob Steenburgh, acting lead of the National Oceanic and Atmospheric Administration's Space Weather Forecast Office. The sunspot's size and growth rate are fairly normal, he said.
It's almost as if people are the problem.

Re: Sunspot activity in freefall
On the other hand, a massive solar flare event is pretty much in like with the last 6 years so I expect at least some power grid failures.

Re: Sunspot activity in freefall
The sun’s activity is peaking sooner than expected
Over the course of a solar cycle, the sun will transition from a calm to an intense and active period. During the peak of activity, called solar maximum, the sun’s magnetic poles flip. Then, the sun will grow quiet again during a solar minimum.
Initially, peak activity was forecast to begin in July 2025. Now, experts believe the cyclical peak is more likely to take place in mid- to late 2024.
