SOLAR CYCLES AND INCREASED SUNSPOT ACTIVITY
Detailed Description
The graphic shows the last 17 solar cycles and their related increased sunspot activity. A solar cycle is a roughly 11-year periodic change in the Sun characterized by variations in the number and intensity of sunspots, as well as a flipping of its magnetic poles.

5 Geomagnetic Storms that Reshaped Society
Every 11 years the Sun's magnetic field flips. This period is referred to as a solar cycle. As we approach the peak of Solar Cycle 25, activity on the Sun’s surface will increase, including more solar flares, sunspots, and coronal mass ejections. If one of these events is directed towards Earth, it could cause a magnetic storm and disturb our planet’s geomagnetic field. A geomagnetic storm may...
