List of solar cycles

The following is a list of solar cycles (sometimes called sunspot cycles), tracked since 1755.Kane, R.P. (2002).

Multiple cycles can be ongoing at the same time as sunspots from old cycles can coexist with sunspots from new cycles. Phillips, A. (2008). " [http://science.nasa.gov/headlines/y2008/28mar_oldcycle.htm Old Solar Cycle Returns] "."Science @ NASA".]
