Geomagnetic storms are coming again!
China Meteorological Administration
Issued by the National Space Weather Monitoring and Warning Center
At around 03:15 on August 9, Beijing time
Solar active zone 13777
Burst X1.3 Great Flar
Within tens of minutes of the flare
A large amount of coronal material is thrown outward at high velocity
Formation of coronal mass ejections (CME)
Be affected by it
It could happen in the next three days
Small to moderate magnetic storms
△The area where the eruption occurred was directly opposite the Earth (SDO satellite)
△Coronal material forms an approximate spherical interplanetary propagation (SOHO satellite)
△Solar activity area and atmospheric monitoring map (Xihe satellite)
At present, there are many active regions on the surface of the sun, in addition to the 13777 that made the CME, the active area 13780 is more worthy of our attention, its area has exceeded 1280uh, and the magnetic field structure is more complex β-γ type, which is likely to create large-scale explosive activities in the future.
A little more news: what is a geomagnetic storm
A geomagnetic storm is a typical type of solar eruptive activity. When the Sun erupts, coronal mass ejections occur, and a single ejection can throw hundreds of millions of tons of solar material off the surface of the Sun at high speeds 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 contain the kinetic energy of the massive mass and velocity, but also carry the powerful magnetic energy of the sun. Once they hit the Earth, they trigger a change in the direction and magnitude of the geomagnetic field, known as a geomagnetic storm.
The geomagnetic storm warning level >>
There are four levels of geomagnetic storm warning from low to high: blue, yellow, orange and red. As an intense 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 largest energy level.
Geomagnetic storms can be classified into the following levels:
What are the effects of geomagnetic storms on life?
Previously, topics such as solar flares and geomagnetic storms continued to rush to the hot search, causing concern and discussion. Some netizens said that the geomagnetic storm has brought more or less impact to their bodies.
"I've been so sleepy lately, I want to sleep when I have a little time" "I've found the reason why I can't sleep" "Is it normal to be not only sleepy but also hungry?" "The reason why I can't sleep has found ......" and "Geomagnetic storm drowsiness" have once rushed to the hot search.
Experts responded that even if there was an X-class flare and a super-geomagnetic storm in May this year, ordinary people may not have too strong personal feelings, and it will not affect their health, let alone special protection.
However, strong geomagnetic activity may affect the animal's ability to migrate and navigate. For example, for carrier pigeons that are navigated by the sun and geomagnetism, the impact is greater.
But on a global scale, it has affected the various technological systems that humans operate in space and on the ground.
