Do sunspots in the sun have anything to do with flares?

Matter. A flare is a phenomenon of intense activity that occurs between the sun's chromosphere, the chromosphere, and the corona's transition layer, also known as chromosphere explosion. It is ferocious, surprisingly energetic, brightening in just a few minutes, usually within hours, but sometimes up to hours or even a day.

A very large flare can release energy of up to 10 (25 to the 26th power) joules, which is equivalent to the energy of hundreds of thousands to millions of strong volcanic eruptions combined. Flare activity is related to the solar magnetic field, and the solar activity cycle is particularly numerous. When sunspots increase, flares also occur frequently, often near sunspots and sunspot groups.

The burst emits visible, ultraviolet, X-ray, ray, infrared, and radio radiation, as well as streams of high-energy particles. The stream of energetic particles is the solar wind. Statistical analysis of observations accumulated over a long period of time reveals a cycle of about 11 years.

The year with the most occurrence, and the year with the most intense solar activity, is called the "peak solar activity year"; Otherwise, it is designated as the "Year of Solar Tranquility".

Sunspots and flares are like clouds and lightning on Earth. Clouds and sunspots are both observable structures that change over time, while lightning and flares are rapid, large-scale energy releases. Their previous relationship was similar.

Not all clouds can produce lightning. Not all spots can produce flares. In general, small, isolated clouds, such as Cumulus minorus, have a hard time producing lightning.

Small spots alone are also difficult to flare up. Clusters of large convective clouds, such as cumulonimbus clouds, are prone to lightning. Large, distorted sunspot swarms are prone to flares.

Sometimes, lightning can occur in places where there are no clouds, and flares can occur in places where there are no sunspots (such as flare events associated with dark streaks in quiet areas of the sun).

<> stars are also planets, and apart from the Earth's outer shell, they look no different from the Sun. A flare is a volcanic eruption (the corona is the atmosphere of the sun) and sunspots are rainy ("Low-temperature plasma hydrogen swarm (I don't know how to describe the material composition of the sun converges downward) flares, direct impact on the Earth's magnetic field may cause communication interference, power grid failures, and only have an impact on humans, but it will not have any effect on the Earth.

The other planets in the solar system do not have liquid water, because they do not like our strong magnetic field, high-energy particles directly destroy the atmosphere, ionizing water, all) will destroy the sunspots needed for life generally have little effect, but if there are more of them, it will cause the temperature of the earth to drop, after all, we only get 2.2 billion parts of energy from solar radiation; Even if this spot is 10% of half of the sun's surface area, 5% of the sun is nothing. This is devastating in the long run. Ice age.

The sun's blackness is either a substance with energy that occurs inside the sun. Frequent activity of black and drug spots can affect the Earth's temperature and magnetic field.

I think the only connection is that it's all due to the heat that comes out of the sun, sunspots are in the interior of the sun, and flares are on the surface of the sun.

There is no relationship, these two things are two completely different substances, and there is no intersection between them.

There are some very special connections that sunspots are visible to our naked eyes, and generally speaking, where there are more sunspots, there may be more sunspots.

Sunspots: There are sometimes dark areas on the surface of the sun's photosphere, which is where the magnetic field gathers, and this 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 drops from 6,000 degrees Celsius to 4,000 degrees Celsius, and the 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.

Solar flare: A solar flare is one of the most violent eruptions that occur in a local area of the solar atmosphere, releasing a large amount of energy in a short period of time, causing instantaneous heating in the local area, emitting various electromagnetic radiations outward, and accompanied by a sudden increase in particle radiation.

Because the background radiation of the solar photosphere is too strong, most flares cannot be observed in white light, and the radiation enhancement is mainly on certain spectral lines, among which the h line of hydrogen (wavelength 6563 angstroms, orange-red color) and ionized calcium h, ** (wavelengths 3968 and 3934 angstroms, respectively) are the most prominent. When monitoring the solar chromosphere with these monochromatic lights, a sudden brightening of small localized areas is sometimes seen in spectral spots near the active region. The brightness of the brightening region is rapidly brightened several times or even dozens of times in a few minutes, and then slowly recovers to the original brightness of the spot within tens of minutes to 1 2 hours.

The following is compiled by myself and I hope it will be useful to you.

1.Sunspots: It is a kind of solar activity that occurs in the photosphere of the sun, and is the most basic and obvious activity phenomenon in solar activity.

Sunspots are thought to be actually giant swirls of hot gas on the surface of the Sun, with a temperature of about 4,500 degrees Celsius. Because the surface temperature of the photosphere is cooler than the sun's, it looks like dark spots. Sunspots rarely move alone.

Often in groups.

2.Flare: The phenomenon of sudden brightening and rapid enhancement of a small local area in the solar chromosphere, also known as chromosphere explosion, is the most dramatic phenomenon in various solar activities.

3.Sun: The chromosphere is a strong rising air flow from the outer sail of the sun, and its edges are jagged, and the huge column of gas that rises particularly high is called the sun.

4.Solar wind: The corona is far away from the surface of the sun, and its high temperature makes the high-energy charged particles move outward at high speed, like the general "wind" blown by the sun, and constantly fly into the interstellar space, commonly known as the "solar wind".

5.Magnetic storm: If for some reason, the solar wind is relatively strong, it will have a violent effect on the earth's magnetic field, and this violent effect is called a magnetic storm, such as radio communications can be affected by magnetic storms.

6.Solar Constant:

1. Sunspots occur in the photosphere, and flares occur in the chromosphere.

2. Sometimes there are some dark areas on the surface of the sun's curved photosphere, which is 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.

3.

On the photosphere of the Sun, there are some swirling air currents, like a shallow disk, concave in the middle, which appear to be black, and these vortex air currents are sunspots. The sunspot itself is not dark, and since its temperature is one or two thousand degrees lower than that of the light sphere, it looks much dimmer against the background of the brighter light ball.

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.

Internationally, it is stipulated that the sunspot cycle from 1755 onwards is the first week, and then in order.

On September 1, 1859, two British astronomers saw a large field of bright flashes emitting dazzling light near a large group of complex sunspots at the same time. The light passed through the sunspots, slowly dimming in brightness until it disappeared. This is the most intense activity phenomenon on the sun – flares.

Because this flare is particularly powerful and can also be seen in white light, it is also called "white light flare". White flares are extremely rare and only occur at the peak of solar activity. Flares usually last only a few minutes, and some flares can last for several hours.

A large amount of energy is released when a flare appears, and the total energy released by a very large flare is as high as 1026 joules, which is equivalent to the total energy of 10 billion megaton hydrogen bombs**. The flare will also radiate a large amount of ultraviolet rays and X-rays, and after reaching the earth, it will seriously interfere with the absorption and reflection of radio waves in the ionosphere, so that some or all of the short-wave radio waves will be absorbed, and the short-wave will be weakened or even completely interrupted.
