More than you ever wanted to know about solar cycles

I found this paper and thought some of you would be interested. Warning:
things look grim from 2019 to 2055 since we'll be in a grand solar
minimum.  Looks like the next three 11 year cycles will not be too
good.  Better prepare space for your 160 m antennas.


  Oscillations of the baseline of solar magnetic field and solar
  irradiance on a millennial timescale

It does get a bit dry but the math is minimal.

The evidence has already made this article obsolete.  No grand minimum.

When the financial crisis hit in 2008 I stopped opening my 401(k)
statements for a couple years.

I think I might do the same with propagation forecasts.

Don't worry, be happy!

I think it's fascinating. Anyhow, it's nice to hear a solar activity
analysis that is based upon science. I half suspect that some of the
sunspot predictions we've heard are made by ex stock market quants and
commodities chartists; it wouldn't surprise me if they started referring
to inverse head and shoulders, cup and handle patterns, sunspot
breakouts, etc.

On the bright side (pun), if there is a long spell of inactivity in the
solar magnetic field it will allow more cosmic rays to hit the earth's
ionosphere which will help light it up a bit. Not sure if that is much
of a silver lining for HF radio but it is something.
