I will do my darnedest to stick around 'till have the sun's life has been
reached ... or at least to go fishing with Leroy.

When stars reach middle age, half of ~10 billion for our sun,they phase into
a state where there are no sunspots for the rest of their hydrogen burning

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 close
third.

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.
