Moon over the Tortolitas

7:09 PM.
7:09 PM. No visible sunspots on the “moon” either.  Did you know that a long absence of sunspots, such as in the Maunder Minimum, was coincident with cold weather, such as that during the Little Ice Age, (though only a part of it)?  A widely accepted causal relationship between sunspot activity and climate has not been established and findings of such relationships are usually considered controversial.
