Solar Cycles 21, 22 and 23:A Graphical Comparison
Solar cycle 23 was originally predicted to reach the same magnitude as cycle 21.
A peak somewhere between 115 and 145 is more likely, based on the development of cycle 23. Cycle 22 is not a good comparison due to the unusually short time it took to reach its maximum.The X axis in the chart is the number of months since the cycle started, while the Y axis is the sunspot number.
