The mag flux is too weak.
I think this is a speculative connection... I don't see it as something that enough is known about.
We may be seeing an extended absence of sun spots, we can see that they are trying to form, but they can’t.
We've seen, in our recorded history, a longer and more extended absence of sunspots than what we see now.
As to what they are "trying" to do and what they "can and cannot do" -- that's speculative, too.
Flash forward 20 years, a father talks to his son and says when I was little we still had sun spots. In other words, they may be history.
Again, this is more speculation. There is way too much guesswork to say one way or another. Furthermore, since we've seen more severe and a much more extended time of no sunspots in our recorded history, I would say that we're far, far from being able to even "speculate" down that pathway (based on our own historical record).
There is a lot of speculation in here, but what isn’t speculation is the requirement for a min mag flux threshold.
As far as when this will end etc.. pure speculation.
But the mag flux will need to increase for sun spots to return.
