Solar Cycle 25 began in December 2019 and is expected to peak around 2025. So far, Solar Cycle 25 has been relatively quiet, with fewer sunspots and solar flares than previous cycles. However, as the cycle progresses towards solar maximum, we can expect to see an increase in solar activity. Scientists are closely monitoring the Sun''s activity ...
The Short Answer: The solar cycle is the cycle that the Sun’s magnetic field goes through approximately every 11 years. Our Sun is a huge ball of electrically-charged hot gas. This charged gas moves, generating a powerful magnetic field. The Sun's magnetic field goes through a cycle, called the solar cycle.
Here’s how it works. The solar cycle describes an approximately 11-year cycle of solar activity driven by the sun 's magnetic field and indicated by the frequency and intensity of sunspots visible on the surface. Solar cycles are repetitive yet difficult to predict.
The beginning of a solar cycle is a solar minimum, or when the Sun has the least sunspots. Over time, solar activity—and the number of sunspots—increases. The middle of the solar cycle is the solar maximum, or when the Sun has the most sunspots. As the cycle ends, it fades back to the solar minimum and then a new cycle begins.
Since then, we have officially gone through 24 complete solar cycles. Solar cycle 24 began in December of 2008, where sunspots and overall activity were at a minimum. Its maximum activity was reached in April 2014. For the last two years (2019 and 2020), the sun has been pretty quiet with a record-setting low number of sunspots.
Evolution of magnetism on the Sun Solar cycles have an average duration of about 11 years. Solar maximum and solar minimum refer to periods of maximum and minimum sunspot counts. Cycles span from one minimum to the next. Samuel Heinrich Schwabe (1789–1875), German astronomer, discovered the solar cycle through extended observations of sunspots.
The Sun follows a roughly 11-year rhythm of waking up and becoming very active before calming down again, a stellar beat known as the solar cycle. This affects Earth because it shapes space weather, determining how much radiation, magnetic field and particles the Sun flings out into space and towards our planet. What is the solar cycle?

solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences are repeated. Sunspot groups have a magnetic field with a north and a south pole, and, in each 11-year rise and fall, the same polarity leads in a given hemisphere while the opposite polarity leads in the other. In each rise and fall, the latitude of …
The solar cycle also means the difference between coronal mass ejection-powered geomagnetic storms at solar maximum, which are often short and intense, and coronal hole-powered storms, which can last much longer. During this solar minimum, we are also watching the predictions for the next solar cycle closely, in hope that it will be more active than …
The solar cycle is the cycle that the Sun''s magnetic field goes through approximately every 11 years. Our Sun is a huge ball of electrically-charged hot gas. This charged gas moves, generating a powerful magnetic field.
The solar cycle is a roughly 11-year cycle in the sun''s activity. At the start of each cycle, the sun''s activity is low. It''s at a so-called "solar minimum." Over an average four years, the sun''s activity rises to a "solar maximum." Over another seven years or so, it quiets back down to a solar minimum.
The estimation technique is used to predict the remaining of the current cycle, but it is not able to predict the next solar cycle at this time. However, for engineering applications and mission planning an extended forecast for the next solar cycle is given below. The values shown for the next cycle are those of a mean cycle obtained from averaging previous cycles of …
The Solar cycle, also known as the solar magnetic activity cycle, sunspot cycle, or Schwabe cycle, is a periodic 11-year change in the Sun''s activity measured in terms of variations in the number of observed sunspots on the Sun''s surface.
Solar cycles are periods—or "cycles"—of solar activity. This activity is driven by the sun''s magnetic field and can vary drastically in intensity and length. This intensity is measured by the frequency and intensity of sunspots on the sun''s surface. Sunspots are dark areas on the solar surface that have strong, constantly shifting magnetic fields. Sunspots are cooler than the rest ...

Solar Cycle 25 has begun. The Solar Cycle 25 Prediction Panel announced solar minimum occurred in December 2019, marking the transition into a new solar cycle. In a press event, experts from the panel, NASA, and …
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 field reverses. Then, the Sun settles back down to a …

Sunspots eventually decay, releasing magnetic flux in the photosphere. This flux is dispersed and churned by turbulent convection and solar large-scale flows. These transport mechanisms lead to the accumulation of magnetized decay products at high solar latitudes, eventually reversing the polarity of the polar fields (notice how the blue and yellow fields reverse in the Hathaway/NASA/M…

What is the Solar Cycle? The solar cycle is a nearly periodic change in the Sun''s activity between the time where we can observe the most and least number of sunspots, and generally lasts around 11 years. Sometimes the surface of the Sun is very active with lots of sunspots, while other times it is quieter with only a few or even none.
From our vantage point on Earth, the Sun may appear like an unchanging source of light and heat in the sky. But the Sun is a dynamic star, constantly changing and sending energy out into space. The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Sun is […]
The amount of magnetic flux that rises up to the Sun''s surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle. Near the minimum of the solar cycle, it is rare to see sunspots on the
