Here is NASA's latest data, updated on October 1, for the current sunspot cycle - known as Solar Cycle 24 - and it shows sun spot activity continuing to decline.

"The current predicted and observed size makes this the smallest sunspot cycle since Cycle 14... in February of 1906," states NASA's website for Solar Cycle Prediction managed by the Marshall Space Flight Center in Huntsville Alabama. Each sunspot cycle lasts around 11 years and the number of sun spots is linked to levels of solar irradiance - although the variation in solar irradiance between peak and trough is small.
