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:
“Democracy is the menopause of Western society, the Grand Climacteric of the body social. Fascism is its middle-aged lust.”
—Jean Baudrillard (b. 1929)
“The solar system has no anxiety about its reputation, and the credit of truth and honesty is as safe; nor have I any fear that a skeptical bias can be given by leaning hard on the sides of fate, of practical power, or of trade, which the doctrine of Faith cannot down-weigh.”
—Ralph Waldo Emerson (1803–1882)
