solar storm

According to information on Wikipedia, solar storm Can be born in 4 forms

1. Solar wind
Solar wind is caused by the expansion of the Sun’s corona with higher thermal energy. When it expands until the particles escape the gravitational pull of the sun. and fled from the sun in all directions. to cover the solar system The phenomenon occurs at the north and south poles of the Sun. with a large coronal cavity The coronal cavity is where the high-speed and intense solar wind blows from the sun in that region. While the solar wind that occurs near the Sun’s equator will have low speed The solar wind arising from this expansion of the sun’s equatorial corona It has an average starting speed of about 450 kilometers per second. After that, it will accelerate to approximately 800 kilometers per second.

2. Solar flare
A solar flare is caused by a violent explosion in the chromosphere. And it usually occurs over the junction between the poles of the magnetic field, such as the center of the double black spot. or in the midst of clusters of black dots with complex turbulent magnetic fields which emits energy in the form of light and magnetic waves different types of electricity came out violently but nowadays Astronomers do not yet know exactly the mechanism for solar flares.

3. Corona discharge
Coronal mass ejection (CME) Astronomers do not yet know exactly how this happens. But it has been found to be caused by other phenomena occurring at the lower corona level. often found Occurs in conjunction with solar flares and prominence. But sometimes it may happen without these two phenomena at all. In addition, the birth frequency also varies with the solar cycle. In the vicinity of the solar minimum, it may occur about once a week. If it is near the peak of the sun It may happen as often as two or three times a day.

4. High-energy particles from the sun
High-energy particles from the Sun, or geomagnetic storms, can occur in two ways: the first occurs in conjunction with solar flares. The other is caused by a high-velocity coronal ejection blasting into the solar wind. causing a shock wave to the earth’s magnetic field High-energy solar particles are generated in this shock wave region.

How do solar storms affect the world?

magnetic storm caused by solar wind and corona discharge Solar radiation storms are caused by high-energy particles from the Sun. Radio signal blackouts are caused by solar flares and high-energy particles from the Sun.

NASA watches “Solar Storm” destroys the Earth’s power system
In this case, NASA found that the solar storm is getting more and more intense. And it is expected to peak in 2025 and no one knows what will happen. But it is estimated that there is a chance of more than 10 percent that the global internet system will crash. And if it really happened, it could crash for months.

by scientist It is developing ‘warning’ technology before a solar storm, using AI to process images of phenomena on the sun’s surface. This system can be used to warn about 30 minutes in advance, so that at least Humans will try to maintain the infrastructure working through various techniques. before becoming paralyzed because of the upcoming intense solar storm

side Simon Machin An official in charge of the British Meteorological Agency’s space weather program said:

Current knowledge and tools still can’t notice Or can predict the occurrence of solar storms Because when we notice A solar storm has occurred. But experts still have some way to predict the likelihood of solar storms and systems related to power supply. Which has been used 15-20 years ago, has not tested its ability to withstand solar storms. or a global magnetic storm and if it actually happened There will be only 20 minutes to prepare.

Academics in Thailand are also interesting, such as “Ajarn Chet” Assoc. Lecturer, Department of Biology Faculty of Science Chulalongkorn University provided information that

usually solar wind This is a stream of cosmic rays coming from the Sun. On a regular basis, there will be “circle” of violence increases every 11 years, which will complete in 2025

The point is to avoid problems that may arise from the Internet system. and other electrical systems caused by the effects of the intense solar wind to satellites and power grids (Which I still don’t know how strong it will be. It might not be anything. Or if you think the worst might cause the internet to crash for months) So NASA is trying to develop new technology. In order to detect it in advance, in a timely manner, various systems can protect themselves in time. should not panic

however Teacher Jed stated that

solar wind It has no effect on human health. At most, we could see the Northern Lights. The southern lights are more beautiful by area near the pole does not affect the earth’s surface an earthquake volcanic eruption or the world stops turning Like in the movie too

Go back and read popular news!!

for “Global Magnetic Storm” (geomagnetic storm), also known as “Solar Storm” This is the same mechanism that causes the Northern Lights phenomenon. The US National Oceanic and Atmospheric Administration said A geomagnetic storm occurs when the intense solar wind near Earth interacts with the Earth’s magnetic field and causes a sharp shift in the direction of the plasma and solar wind. which warms the upper atmosphere of the Earth and increase the atmospheric density to a high enough to affect satellites in low orbit. such as Starlink

“SpaceX” loss of communications satellites “Star Link” (Starlink) recently launched into low-Earth orbit. due to the global magnetic storm phenomenon or “Solar Storm” This caused 40 satellites out of 49 to hit Earth.

Space Dot Com (space.com) reported that on February 4, 2022 g,njv at 1:13 am Thailand time, the Falcon 9 rocket, a space transport vehicle of SpaceX Company (SpaceX Falcon 9) launched a mission. Starlink satellites, 49 communications satellites, entered orbit. but all face A geomagnetic storm causes friction in the atmosphere to be higher than normal.

Until later, on February 8, SpaceX revealed that up to 40 Starlink satellites had fallen back into the Earth’s atmosphere. And all burned up, explaining that in every launch, the satellite will be at a lower altitude than the orbit set. Because if the satellite crashes, it will fall back into the Earth’s atmosphere and burn up. Doesn’t cause space junk

As for the launch of the Starlink satellite last week, under the name “Starlink 4-7 mission” (Starlink 4-7) is the company’s third satellite launch mission this year. To send 49 communications satellites to join the other 1,800 Starlink communications satellites in orbit. Continuation on January 31 with the launch of an Italian survey satellite and on February 2 is the launch of a satellite from the United States.

The news states that since 2019 onwards spacex The Starlink constellation is periodically launched. Sometimes as many as 60 satellites form a large constellation of satellites in orbit to provide high-speed internet to customers anywhere in the world. especially in remote areas or disadvantaged areas

However, many astronomers disagree with the project. because that would affect astronomical observations SpaceX is therefore working to limit visibility of Starlink satellites to reduce their impact on the astronomy community.
