Solar cycle predictions are used by various agencies and many industry groups. The solar cycle is important for determining the lifetime of satellites in low-Earth orbit, as the drag
Our Sun goes through what we call a "solar cycle" every 11 years or so. Then, the Sun''s magnetic field completely flips! Learn more
The Sun''s magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun''s magnetic field completely
What is the Solar Cycle? The solar cycle is an approximately 11-year cycle experienced by the Sun. During the solar cycle, the Sun''s stormy behavior builds to a maximum, and its magnetic
Individual sunspots come and go, with lifetimes that range from a few hours to a few months. If a spot lasts and develops, it usually consists of two
One of the most striking features of the sun''s activity is what astronomers call the solar cycle. This is an epic rise and fall in the sun''s level of activity that repeats every 11 years
What is a Solar Cycle? The solar cycle is the approximately 11-year period of change in the Sun''s activity levels. This cycle is characterized by the rise and fall of sunspots,

Because the solar cycle reflects magnetic activity, various magnetically driven solar phenomena follow the solar cycle, including sunspots, faculae/plage, network, and coronal mass ejections.
