That’s an interesting article. Thanks. I looked up the definition for the “grand minimum” - and that event seems like something one might be able to perceive with the eyes (represents a 7 % dip in the output of the sun if I read correctly). But, the grand minimum is slated for sometime between now and 20 years from now. Last one was in 1750, when Thames froze over.
Still … not too sure if related to what I’m seeing.
