There is a direct correlation between sunspot activity and magnetic storms on earth. At the height of the approximately 11-year cycle of sunspot activity, magnetic storms on earth are more intense and are of greater duration. The intensity of some storms requires a few satellites to be put into "sleep mode" to prevent damage. And the effects on things like the power grid are well documented natural phenomenon that is directly linked to sunspot activity.
Sunspot activity affects radio communications. It can cause ionisation of the D and E layers of the ionosphere which allows High frequency radio waves to be bent back toward Earth, providing multiple hop communications.
A sunspot is a region on the Sun's surface that is marked by intense magnetic activity, which inhibits convection, forming areas of reduced surface temperature. See link for further information
The dark spot on the sun is called a sunspot. Sunspots are temporary phenomena on the Sun's surface that appear darker than their surrounding areas due to cooler temperatures. They are caused by magnetic activity and are often associated with solar flares and solar storms.
These magnetic disturbances are known as magnetic storms.
Storms on the surface of the sun, known as solar storms, primarily include solar flares and coronal mass ejections (CMEs). Solar flares are intense bursts of radiation caused by the release of magnetic energy, while CMEs involve the ejection of large quantities of plasma and magnetic field from the sun's corona. These storms can impact space weather, affecting satellite operations, communication systems, and even power grids on Earth. They are driven by the sun's magnetic activity and cycles, particularly during solar maximum periods.

Magnetism. They are magnetic storms.

Magnetic storms, also known as geomagnetic storms, are caused by disturbances in the Earth's magnetosphere, primarily triggered by solar activity. When the Sun releases large bursts of solar wind and coronal mass ejections (CMEs), these charged particles interact with the Earth's magnetic field. This interaction can lead to fluctuations in the magnetic field and increased ionospheric currents, resulting in magnetic storms. These storms can disrupt satellite operations, communication systems, and power grids on Earth.
During the high periods of the sunspot cycle, several times per year; during sunspot minima, only a couple of times per year. Severe solar storms, which can damage electronic equipment and satellites, are fortunately very rare.

These magnetic disturbances are known as magnetic storms.
Sudden disturbances in the Earth's magnetic field are called magnetic storms. These storms are typically caused by solar wind interacting with Earth's magnetosphere, resulting in fluctuations and disturbances in the magnetic field. Magnetic storms can affect a variety of technologies such as power grids, satellites, and communication systems.
