Default The Quiet Sun

Looks like our friend Sol has finally settled into a dull roar

The solar minimum is about at maximum I believe. This mast solar max was
quite long lived highlighted by extreme flaring events and large sunspots.
However, in terms of actual sunspot numbers, it was average.
As this graphic indicates, 1960, 1980, 1990 were loaded. How much does
solar variation affect climate?

Well, we aren't quite at minimum just yet. The current magnetic sunspot
cycle and the next one generally overlap to some degree. Roughly 18
months before the minimum of the old cycle, the first new cycle spots
may begin to appear near 25 degrees north and south solar latitude, with
the few remaining spots from the old cycle straddling both sides of the
equator. So far in the current magnetograms I have yet to see new
groups near the 25 degree latitude range which have opposite polarity
orientation to those currently on the sun, although I expect this to
occur rather soon. Clear skies to you.

Well, is that a prediction? If it doesn't happen, then you have a rather
tasty foot in yo mouth.

Explain yourself if you are capable. Which we doubt.

He is continuing on a campaign of responding to any of EP Guy's links
with "Sucks. Could be anything." The reason is that EP Guy once did
that to someone else. (Check on Google if, for some bizarre reason,
you're actually curious about this.) The point's long ago been made,
in my opinion, so it would be nice if we could get past this and just
look at the links.
