Grand Solar Minimums and Maximums
Grand solar maximums occur when several solar cycles exhibit greater than average activity for decades or centuries. Solar cycles still occur during these grand solar maximum periods but the intensity of those cycles are more intense. Grand solar maximums have shown some correlation with global and regional climate changes.

Famous quotes containing the words grand and/or solar:
“We had heard of a Grand Fall on this stream, and thought that each fall we came to must be it, but after christening several in succession with this name, we gave up the search. There were more Grand or Petty Falls than I can remember.”
—Henry David Thoreau (1817–1862)
“Senta: These boats, sir, what are they for?
Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.”
—William Faulkner (1897–1962)
