1.When there is a large group of sunspots on the sun, the compass on the earth will shake and cannot indicate the direction correctly; Pigeons, who are usually very good at recognizing directions, will get lost; Radio communications can also be severely hampered, or even abruptly interrupted for a period of time, and these anomalies will pose a great threat to the safe navigation of aircraft, ships, and satellites, as well as television faxes, and so on. 2.
Sunspots also cause changes in the Earth's climate. More than 100 years ago, a Swiss astronomer discovered that when there are many sunspots, the earth's climate is dry and agriculture is abundant; When there are few sunspots, the climate is humid and rainy. Zhu Kezhen, a well-known scientist in China, also found out that the centuries in which sunspots were recorded more in ancient Chinese books were also the centuries in which particularly cold winters appeared in China.
Some people also counted the changes in rainfall in some areas, and found that this change is repeated every 11 years, and it is likely that it is also related to the increase or decrease in the number of sunspots.
3.Scientists who study ** have found that when the number of sunspots increases, there are also more sunspots on the earth. **There is a periodicity of about 11 years.
4.Botanists have also found that tree growth also varies with the 11-year cycle of solar activity. Trees grow faster in years with more sunspots; Years with few sunspots grow slowly.
Changes in the number of sunspots can even affect our body, and the number of white blood cells in the human blood also has an 11-year cycle.
Hope it helps.

Let's summarize my previous ones, I hope it helps you.
Hundreds of years ago, it was recognized that the surface of the sun is not calm, but has a lot of activity (eruptions). Examples include sunspots, flares, solar and coronal mass ejections (CMEs). The Sun is currently in the ascending phase of the 24th Solar Week and reaches its maximum in May 2013 (see NASA forecast), which means that the Sun will become more and more active until 2013 and then slowly wane.
Once the high-energy particles produced by the solar eruption come to the earth, it will disturb the earth's magnetic field, and then cause the interruption of some radio communications, such as the interruption of broadcasting, GPS, etc., the destruction of satellites, the reduction of their service life, etc., the destruction of long-distance transmission lines, causing large-scale power outages, the United States and Canada have this precedent, and will also cause harm to high-altitude passengers and crews, analogous to nuclear radiation and so on.
Coronal mass ejection (CME) is an active phenomenon in which material in the outermost atmosphere of the Sun, the corona, overcomes the Sun's gravitational pull and is thrown off the surface of the Sun into outer space for some reason.
The material thrown by the CME is very thin and will not hit the earth like a rock, but this thin material itself has a magnetic field, so if the direction of the CME ejection is towards the earth, it may cause the disturbance of the earth's magnetic field, and then affect human life (mainly broadcasting, communication, long-distance power transmission, etc.).
Since 1755, when people began to study and record solar cycles, 23 have passed, and according to NASA, the activity in week 24 may be weaker than week 23. The Earth's magnetic field has always provided us with a good umbrella, so in addition to normal sun protection, solar activity has not yet been found to have a significant impact on the lives of ordinary people.
The start and end times of the last few solar weeks are as follows.
- 22nd Solar Activity Week.
The beginning and end of the peak --- the 23rd solar activity week
Begins and ends at the peak --- the 24th solar activity week.
Start peaking.

The effects of sunspots on the Earth are:
1. The compass will tremble, or it may not be able to point the direction correctly.
2. Cause some creatures to lose their sense of direction, such as pigeons.
3. Cause some interference of modern tools, such as radio obstruction.
4. It leads to the drying out of the earth's climate and the reduction of crop survival.
5. The movement of sunspots is very low or reduced, which will lead to changes in the earth's climate, such as the climate becoming humid and frequent storms.
A "sunspot" is a dark area formed by the sun, so dark that the sun's rays cannot illuminate it. And this dark area is where the magnetic field is formed after the episode.
And it can be said that "sunspots" are the only most obvious phenomenon of the sun, and you may not believe it, but this is according to the research of scientists, in fact, a medium-sized "sunspot" produced in the sun is about the same size as the earth!
Long-term observations by astronomers have shown that when the intensity of "sunspots" is larger, other phenomena about the sun become more frequent. After the intense movement of the sunspot, a spot will appear in the nearby light sphere, and a spectral spot will appear in the sky above the sunspot, and there may also be a sunspot during the period.
During a total eclipse of the sun, the sun is surrounded by a red ring that usually erupts in the shape of a tongue. Therefore, it is called the sun by scientists, and the sun is one of the signs of solar activity.

Sunspots have an impact on the earth, mainly in the following ways:
1. Influence solar wind:
Sunspots refer to dark spots on the surface of the sun, and their formation is related to the solar cycle. The magnetic field in the sunspot region is stronger than in the surrounding area, causing changes in the speed and density of the solar wind, which affects the Earth's environment.
2. Triggering solar flares and coronal mass ejections
Sunspots are one of the manifestations of solar activity, and they are often closely associated with phenomena such as solar flares and coronal mass ejections. Solar flare bonding is an intense burst of radiation from the surface of the Sun, which releases large amounts of energy and matter, including high-energy charged particles.
Coronal mass ejections, on the other hand, refer to the giant gas bubbles produced on the surface of the sun, which will bring more serious solar wind and magnetic storm effects, and have a greater impact on the environment such as the earth's magnetosphere and ionosphere.
3. Affect the earth's weather
The activity cycle of sunspots is also related to the changes in the Earth's weather. When the sunspots are most frequent, the Earth's climate will also show certain regular changes, such as increased snowfall in the Antarctic region and more summer storms. In addition, the activity of sunspots can also cause changes in the Earth's magnetosphere, leading to errors in weather forecasts and other aspects.
4. Impact on communication and satellite navigation systems:
When sunspots are violently active, they will produce strong effects such as high-energy ionizing radiation and electromagnetic interference, which will interfere with and destroy systems such as communications and satellite navigation. For example, during a strong solar flare in November 2003, a dramatic increase in ionospheric density caused the global GPS system to be interrupted for about 30 minutes.
In summary, the impact of sunspots on the earth is mainly manifested in the influence of solar wind, the triggering of solar flares and coronal mass ejections, the impact of the earth's weather, and the impact on communication and satellite navigation systems. Today, when human society is highly dependent on science and technology and space technology, the impact of sunspot activities on human society has received more and more attention, and relevant research and monitoring work needs to be strengthened.

Sunspots can have an effect on the Earth's magnetic field, for example, the compass may flutter and not be able to point the right direction. It can also cause creatures such as pigeons, which rely on magnetic fields to move, to lose their sense of direction, and the intense movement of sunspots can also dry out the earth's climate and reduce the survival of crops.
The temperature of the sun is about 6,000 degrees, and the temperature of the center reaches 15,000,000 degrees. The formation of sunspots is due to the huge difference between the inner density of the sun and the outer density, and the most obvious phenomenon is sunspots.
When there is a large group of sunspots on the sun, the compass on the earth will shake and cannot indicate the direction correctly; Radio communications can also be severely hampered, even abruptly interrupted for a period of time. More than 100 years ago, a Swiss astronomer discovered that when there are many sunspots, the climate on Earth is dry and agriculture is abundant.
When sunspots are scarce, the climate is humid and rainstorming. This suggests that sunspots also have a great influence on the Earth's climate.
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.
The close relationship between the earth and the sun is self-evident, the sun is the basis of the existence of life on the earth, the source of light and heat on the earth, no matter what conditions and changes it occurs, it will have a very important impact on the earth. Sunspots are a very active phenomenon of matter on the sun, so the impact on the earth is also particularly obvious. >>>More

The surface of the sun's photosphere sometimes appears in dark areas, which are where the magnetic field gathers, known as sunspots. And how do sunspots affect the Earth's climate? While the scientific community is still inconclusive about this, there are some theories.
Although there is a [Sanhe] auspicious star entering the palace this year, you can get the support of nobles to bring financial gains, but if others propose opportunities for cooperation and development, this year is not a suitable year, the development plan is not yet mature, there is no specific development process, everything is only a preliminary stage, everything must be done with a cautious attitude. This year, we should be mentally prepared for "more work and less reward", and we might as well regard this year as the "sowing period", and we can expect to harvest next year. At the same time, it is necessary to pay attention to prudent words and deeds and clerical contracts to prevent the loss of money and property caused by provoking official wrongdoing. >>>More
