Getting predictions right is really hard ... especially if they're in
the future.

When stars reach middle age, half of ~10 billion for our sun,they

So the sunspots cycle ( which is ~22 years by the way, it is based on
sunspot polarization, ~11 years is half of the cycle. ), will
disappear completely. I did see
a sunspot group when I looked at the sun in Hydrogen alpha, so not
today.
Amateur astronomy and radio are the coolest hobbies, with fishing a

Subject: [Elecraft] Solar Cycles
For those who have been concerned whether the solar cycle would
reverse this time, take heart. An article in The Economist for Jan.
21 2017 (at page 67) reports that a study of fossilized vegetation
from the Permian period about 290 million years ago evidences a solar
cycle back then of 10.6 years, easily within the statistical
variability around today’s 11.2.
Take that, Annie and Walter Maunder.
