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 https://www.nature.com/articles/s41598-019-45584-3 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! 73, Carl WS7L On Mon, Jun 24, 2019 at 6:56 PM kevinr <[hidden email]> wrote: > I found this paper and thought some of you would be interested.

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. 73, Drew AF2Z On 06/24/19 21:55, kevinr wrote: > I found this paper and thought some of you would be interested.
