The question of the activity of sunspots, the activity cycle of sunspots

The average period of sunspot activity is 11 years. In the first four years or so, sunspots continue to be produced, more and more, and the activity intensifies, and the year when the number of sunspots reaches a high is called the peak year of solar activity. In the following 7 years or so, the sunspot activity gradually decreases, and the sunspot number becomes less and less, and the year when the number of sunspots is extremely small is called the solar activity valley year.

Sunspots are areas on the sun that are cooler than other regions, so they look black and are often accompanied by strong magnetic activity, and the activity cycle of sunspots is 11 years, but this does not mean that sunspots can exist for 11 years. The sunspot event dissipates after it ends, how can it be active for so long.

There should be no change.

Sunspots, I only know that he is a whirlwind around the sun, which has a strong radiation effect on the earth, and it is black from the earth, so it is called sunspots, and I don't know what has changed.

SunspotsThe cycle of activity is years.

The surface of the sun's photosphere sometimes appears in some dark areas, which are where the magnetic field gathers, which is the sunspot.

Sunspots are the most prominent phenomenon that can be seen on the surface of the sun.

A medium-sized sunspot is about the size of the Earth.

The formation and disappearance of sunspots can take anywhere from a few days to a few weeks.

When a strong magnetic field emerges on the surface of the Sun, the background temperature of the region slowly rises from 6000 degrees Celsius.

Dropping to 4000 degrees Celsius, this region appears as a dark spot on the surface of the sun.

The darkest part of the center of the sunspot is called the umbra, and the umbra is the area where the magnetic field is strongest.

The not-so-dark, striped area around the umbra is called the penumbra.

Sunspots rotate with the surface of the sun, completing one rotation after about 27 days.

Long-term observations have found that when there are many sunspots, other solar activities will also be more frequent.

There will always be spots in the ball of light near the sunspots, and there will always be spectral spots in the balls of color above the sunspots, and there are often suns in the vicinity.

At the same time, the vast majority of solar eruptions also occur in the atmosphere over sunspots.

Therefore, from the lower to the upper layers of the solar atmosphere, sunspots form an activity center, that is, the solar activity zone, with sunspots as the core.

The sunspot is not only the core of the activity area, but also the most obvious symbol of the activity area.

The sunspot cycle has many key points, and here are five of the important ones:

1. Sunspot maximum:

A key feature of the sunspot activity cycle is the peak of the number of sunspots, also known as the maximum of solar activity. In each cycle, the highest number of sunspots on the surface of the Sun is present, which is usually the most active time of the cycle. The maximum of sunspots usually accompanies the peak of solar activity, with frequent flares and eruptions.

2. Sunspot minimum:

Corresponding to the maximum of the solar cycle is the minimum of sunspots, also known as the minimum of solar activity. This is the period when the number of sunspots is lowest in the cycle, and solar activity is calmer. During the minimum, the number of sunspots decreases and the magnetic field activity is relatively weak.

The duration of the sunspot activity cycle is an important key point. Typically, the time it takes for a complete cycle to go from one sunspot maximum to the next sunspot maximum is about 11 years. However, the exact duration of the cycle may vary and may be between 9 and 14 years.

4. Changes in the sunspot cycle:

The characteristics of sunspot activity cycles are not exactly the same, and there may be some slight variations in each cycle. For example, sometimes the maximum number of sunspots in a weekly high sentence may be larger or smaller than in the previous period. These changes may be related to the complexity of the Sun's magnetic field and other factors.

5. Phenomena that affect the earth:

The sunspot cycle is associated with a number of phenomena on Earth. During active periods, an increase in sunspot count can lead to solar flares, eruptions, and the enhancement of the solar wind. These activities can produce energetic particles and have an impact on the Earth's filial magnetic field and ionosphere, leading to the appearance of auroras and affecting electromagnetic communications and space weather.
