Solar Maximum - Grand Solar Minimums and Maximums

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:

    There is the grand truth about Nathaniel Hawthorne. He says NO! in thunder; but the Devil himself cannot make him say yes. For all men who say yes, lie; and all men who say no,—why, they are in the happy condition of judicious, unincumbered travellers in Europe; they cross the frontiers into Eternity with nothing but a carpet-bag,—that is to say, the Ego. Whereas those yes-gentry, they travel with heaps of baggage, and, damn them! they will never get through the Custom House.
    Herman Melville (1819–1891)

    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)
