History of sunspot number observations showing the recent elevated activity.
The Modern Maximum refers to the ongoing period of relatively high solar activity that began circa 1900.[1] This period is a natural example of solar variation, and one of many that are known from proxy records of past solar variability. The Modern Maximum reached a double peak once in the 1950s and again during the 1990s.
