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.

An increase in sunspot activity can affect Earth's climate by causing fluctuations in temperature and weather patterns. It can also lead to disruptions in satellite communications and power grids due to increased solar radiation and geomagnetic storms. Additionally, it can impact the Earth's magnetic field and auroras.
every eleven years lol
The sunspot cycle lasts around 11 years. It is characterized by a period of increasing sunspot activity, followed by a period of decreasing activity.
The average sunspot cycle is approximately 11 years, with periods of high sunspot activity followed by lower activity levels. This cycle is known as the solar cycle or the sunspot cycle.
The solar phenomenon that wouldn't be expected to increase with an increase in sunspot number is the solar wind speed. Sunspot number correlates with solar activity and can affect phenomena like solar flares and coronal mass ejections, but the solar wind speed is more influenced by other factors like the temperature and density of the solar wind source regions.
Sunspots are unpredictable and can occur at any time. They follow an 11-year solar cycle, with peaks of sunspot activity happening roughly every 11 years on average. The next peak of sunspot activity is expected around 2024-2025.
