Solar maximum is years past, yet the sun has been remarkably activ |
NASA Science News for November 12, 2003
Solar maximum is years past, yet the sun has been remarkably active
lately. Is the sunspot cycle broken?

From the article:
"Nothing's wrong," reassures Hathaway. The sun isn't about to explode, nor is
the sunspot cycle broken. "These latest sunspots were whoppers," he allows,
"but sunspot counts averaged over many weeks are still declining as predicted.
We're still on course for a solar minimum in 2006."

Must be the gravity of that danged ol' Planet X. If you look at Nutty Nancy's
website, it's apparently stalled between us and the sun. Been there since May.

Thanks Sam,
If you read into the data it actually seems "normal" for some of this
activity to happen after the solar maximum.
What causes the 11 year cycle of sunspot activity? I have seen a lot of
material "about" the 11 year cycle but never anything about "what causes"
the cycle. It's interesting that such a large body has such a cycle and I
would be interested in learning more about the reasons behind it. Is this
some sort of internal clock of the suns and if so what does it mean? If not
internal - what external force would influence such a large body in such a
way?
Thanks,

They don't know.
That or how the IMF works.
