"11.000 year Solar Record & Angular Momentum" (9400BC - 2000AD)
Solar activity events recorded in radiocarbon. (Note: reverse time-scale!) [1] (1200AD - 1960AD)
Maunder Minimum is the name given to the period roughly spanning 1645 to 1715 (graph time-span: 1645-2000). During one 30-year period within the Maunder Minimum, astronomers observed only about 50 sunspots, as opposed to a more typical 40,000–50,000 spots in modern times.
Note: also the Dalton Minimum (1790–1820) (see also: Year Without a Summer)
Sunspot cycles (1749-2003) [2]
Annual sunspot numbers (1800-1993) [3]
Sunspot index 1997-2008 [6]
Average Solar Magnetic Index from 1991 to 2008-10-6 [7].
See also: "Solar Cycle 24 Begins".
Solar maximum 1999 [8]
