Answer: The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle.
The Sun is currently in Sunspot Cycle 24 which began on January 4th 2008. Cycle 24 is expected to reach a sunspot maximum of 89 in May of 2013. Original predictions for cycle 24 had placed the number of spots below the exceptionally low 1907 number of 64.2 (cycle 14).
