"It's horrible, it is recommended to extend the holiday by 3 days!"
On the first day of post-holiday rework,
The solar flare has caused heated discussions among netizens on social media.
National Space Weather Monitoring and Warning Center
A yellow flare warning was issued
Beijing time 14:01 on May 5, 2024
The sun erupted with a strong flare (magnitude X1.3)
The continent was daylight at the time of the event
The flare had an effect on the ionosphere over the continent
Expected in the next 2 days
There is still a possibility of an M-class or even X-class flare or higher
National Space Weather Monitoring and Warning Center
The development of events will be closely followed
Timely release of forecast and early warning information
The resurgence of solar flares
It has aroused widespread attention and discussion among netizens
Solar flares can be on Earth for us
What is the impact?
What is a solar flare?
Solar flares are one of the most intense activity phenomena on the Sun. The main observation characteristics are that the local area of the solar atmosphere suddenly brightens, often accompanied by the enhancement of electromagnetic radiation and particle emission in various energy bands, and the brightness rises rapidly and decreases slowly.
Although the lifespan of a solar flare is only between a few minutes and tens of minutes, the energy released is equivalent to the total energy of 100,000 or even a million powerful volcanic eruptions, or equivalent to the explosion of tens of billions of hundred-ton hydrogen bombs.
As a strong energy eruption on the surface of the sun, solar flares are divided into five levels: A, B, C, M, and X, of which A is the least energetic level and X is the maximum energy level.
On average, every 11 years, solar activity will show a cyclical change from weak to strong, and then from strong to weak, which is the solar activity week. It is currently in the 25th solar week of bounty, and the Sun will reach the peak of its current activity cycle in 2024.

What are the implications for us on Earth?
A flare is like a "sneeze" from the sun, and the earth may also "catch a cold".
The damage caused by a solar flare outbreak to the Earth usually depends on the level of the flare, its duration, and the amount of energy released. In general, the X-class is the strongest flare class and has the potential to have a significant impact on Earth and potentially cause a "space weather disaster".
These disasters are mainly emitted by the sun in the form of radiation and energetic materials, affecting near-Earth space as well as man-made facilities on the ground. For example, solar flares will affect the Earth's ionosphere on the sunny side, short-wave communications, navigation and positioning, maritime search and rescue, some emergency communications, and even mobile phone communications may be interfered with, and long-distance high-voltage power transmission systems and oil pipelines on the ground will also be affected.
This kind of disaster is gradually becoming prominent with the progress of human space science and technology, especially the impact and harm on the safety of satellites and spacecraft, aviation, communications, navigation and other fields.
How can I reduce the effects of solar flares?
Since the first solar cycle was observed in 1755, humanity is now experiencing an upward phase of the 25th solar cycle. It can be expected that solar activity will gradually increase and that solar flares and coronal mass ejections will occur more frequently.
The sun is so "vibrant", how can we guard against it?
There is no need to panic, the Earth has its own "gas mask" - the magnetic field, which helps us block most of the high-energy particles from the solar eruption.
In addition, scientific researchers will track the eruption of the solar atmosphere in a timely manner through various types of solar observation equipment, do a good job of space weather forecasting and early warning, selectively turn off the power grid during special periods, and adjust communication systems, aircraft routes or satellite orbits in time to minimize the impact of solar activities.
Geomagnetic storms are not all bad, such as the occurrence of aurora celestial phenomena, if the geomagnetic storm is particularly strong, and even further south it is possible to see the aurora.
