The National Space Weather Monitoring and Warning Center introduced on the 15th
At 23:29 on September 14th, Beijing time
An obvious flare broke out in the solar active area 13825
Its peak intensity was x4.5 level
It reached the large flare level
When the flare occurred Our country is in the night
, so it has no impact on our country's ionospheric weather.
Based on the currently obtained position of the solar active area
coronal mass ejection velocity
and the relative position relationship with the earth, it can be judged
that the coronal mass ejection that occurred on the evening of 14th
may be in A series of space environment changes that will affect the earth from September 16 to 17 will likely occur, including geomagnetic storms
an increase in the density of the upper atmosphere
ionospheric storms
which will have varying degrees of impact on aerospace, communications and other fields

Currently, it is the time for the autumn competition of homing pigeons. A large number of racing pigeons are soaring on their way home. This reminds the majority of homing pigeon players to pay more attention to the trends of space weather and ground weather in the future. , comprehensive research and judgment, careful management, and reduce unnecessary losses.
In addition, based on the prediction of the intensity of possible geomagnetic storms, aurora activity may occur in my country, but due to the influence of the full moonlight during the Mid-Autumn Festival, the observation effect may be slightly worse. The bright moonlight weakens the aurora effect to some extent.

What is a geomagnetic storm?
Geomagnetic storm is a typical solar explosive activity. When the sun explodes, a coronal mass ejection occurs. A single ejection can throw billions of tons of solar material away from the sun's surface at a high speed of hundreds to thousands of meters per second.
Han Dayang, a senior engineer at the Space Weather Technology R&D Office of the National Space Weather Monitoring and Warning Center of the China Meteorological Administration, said, "Geomagnetic storms are neither visible nor perceptible to humans."
These substances not only include huge masses and The kinetic energy gathered by the speed also carries the sun's powerful magnetic field energy. Once they hit the earth, they will trigger changes in the direction and size of the geomagnetic field, known as geomagnetic storms.
There are 4 levels of geomagnetic storm warning levels from low to high: blue, yellow, orange, and red.
Solar flares are intense energy eruptions on the sun's surface and are divided into five levels: a, b, c, m, and x. A is the minimum energy level and x is the maximum energy level.
Geomagnetic storms can be divided into the following levels:
Do geomagnetic storms cause drowsiness? What impact does
have on life?
Previously, topics such as solar flares and geomagnetic storms continued to be hot searches, triggering attention and discussion. Some netizens said that the geomagnetic storm had more or less impact on their bodies.
"I've been so sleepy recently and want to sleep after a while." "I found the reason why I can't sleep." "I'm not only sleepy but also addicted to eating. Is this normal?" "I found the reason why I can't wake up..." "Geomagnetic storm sleepiness" "The entry once became a hot search topic.
Experts responded that even if an X-level large flare and a super large geomagnetic storm occurred in May this year, ordinary people may not feel it personally, and it will not affect their health, and there is no need for special protection.
Zhang Bin, director of the Sleep Research Laboratory and chief physician of the Department of Psychiatry at Nanfang Hospital of Southern Medical University, told reporters, "In the outpatient clinic, there are not many patients who come to see us due to drowsiness caused by geomagnetic storms."
Han Wenbiao, a researcher at the Shanghai Observatory of the Chinese Academy of Sciences, told reporters , " There are no relevant studies showing that solar flares can cause headaches and insomnia. During strong flares, you can wear sunglasses and apply sunscreen for protection. strong flare events may have some effects on the human body, such as eye fatigue, skin sunburn, etc., but these effects will only occur under very extreme circumstances. ”
This year and next will be the period of high solar activity.
According to previous reports, this year and next year will be the period of high solar activity. The public may often see flares and geomagnetic storm warnings, so there is no need to be surprised.
National Space Weather Monitoring and Warning Center Director Wang Jinsong previously introduced at a press conference held by the China Meteorological Administration that monitoring shows that this solar activity cycle has entered the peak stage. According to the latest research and judgment, the peak of this solar activity cycle is expected to arrive in 2024 to 2025. At present, It is near the peak, and solar activity is relatively frequent, which is a normal natural phenomenon.
He said that this year to next year will be the peak year of solar activity, which means that there will be some space weather events such as solar flares and geomagnetic storms in the future. You can maintain a normal mind and treat the impact of space weather events scientifically. "Although geomagnetic storms will have a certain impact on the operation of spacecraft, they will have minimal impact on people's health and daily life, and the public does not need to worry." "
