Solar maximum is the regular period of greatest solar activity during the Sun 's 11-year solar cycle . During solar maximum, large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%. 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.

10-427: A solar maximum in 2010 or 2011, and thought that it could be the strongest since 1958 . However, the solar maximum was not declared to have occurred until 2014, and even then was ranked among the weakest on record. In addition to the ~11 year solar cycle, the intensity of the solar maxima can vary from cycle to cycle. When several solar cycles exhibit greater than average activity for decades or centuries, this period
15-467: Is labelled "Grand solar maximum". Solar cycles still occur during these grand solar maximum periods, but the intensity of those cycles is greater. Likewise, extended periods in which the solar maximum is lower than average are labeled "grand solar minima". Some researchers suggest that grand solar maxima have shown some correlation with global and regional climate changes, although others dispute this hypothesis ( e.g. , see Medieval Warm Period ). Following
20-475: The Carrington Event , which took place a few months before the solar maximum of solar cycle 10 , was the most intense geomagnetic storm in recorded history and widely considered to have been caused by an equally large solar storm. Predictions of a future maximum's timing and strength are very difficult; predictions vary widely. There was a solar maximum in 2000. In 2006, NASA initially expected
