[citation needed] On average, the solar cycle takes about 11 years to go from one solar maximum to the next, with duration observed varying from 9 to 14 years. Three recent solar cycles Large solar flares often occur during a maximum.
An example of a recent sunspot cycle spans the years from the solar min in 1986, when 13 sunspots were seen, through the solar max in 1989 when more than 157 sunspots appeared, on to the next solar min in 1996 (ten years after the 1986 solar min) when the sunspot count had fallen back down to fewer than 9.his solar cycle is, on average, about 22 years long-twice the duration of the sunspot cycle. Some scientists believe there is evidence for other, longer-period variations in the sunspot and solar cycles.
