Moderate to geomagnetic storms are likely to occur on 6 October
A small geomagnetic storm is likely to occur on the 7th
What are flares and geomagnetic storms?
A flare is one of the most violent activity phenomena on the sun, usually embodied in a sudden and large-scale energy release process in a local area of the sun's surface, causing instantaneous heating of the local area, emitting various electromagnetic radiation outward, accompanied by a sudden increase in particle radiation, just like a person sneezing. Solar flares are divided into five levels: A, B, C, M, and X, with X being the most energetic level.
A geomagnetic storm is a typical type of solar eruptive activity. According to Tang Yunqiu, deputy director of the Space Weather Forecasting Station of the National Satellite Meteorological Center, when the sun erupts, coronal mass ejections will occur, and a single ejection can throw hundreds of millions of tons of solar materials away from the surface of the sun at a high speed of several hundred to several thousand meters per second.
Why can geomagnetic storms be warned?
When a coronal mass ejection or solar flare erupts, it travels to Earth at the speed of light, which is known about 8 minutes after the solar activity occurred.
The Sun's stream of charged particles travels much slower, taking about two or three days to reach Earth, so humans can warn of possible geomagnetic storms.
Why are geomagnetic storms so frequent this year?
The solar eruption activity is characterized by a cyclical variation of about 11 years. The 25th solar cycle began in 2019 and is now at its peak. According to experts, this year and next year are both periods of high incidence of solar activity, and there may be some space weather events such as solar strong flares and geomagnetic storms in the future, which are normal natural phenomena.
Will human activities be affected?
Tang Yunqiu, deputy director of the Space Weather Forecasting Station of the National Satellite Meteorological Center, said that geomagnetic storms will have an impact on satellite communications and spacecraft operations. The space station may decrease its orbital altitude due to increased atmospheric drag, and the positioning error of satellite navigation equipment may also increase. Aviation flights will also face the dual risks of deterioration of the communication environment and radiation in the transpolar region.
For ordinary people, the most intuitive experience of a strong geomagnetic storm is that the aurora phenomenon may be observed in the high latitudes of the northern part of the continent.
Will human health be affected?
Geomagnetic storms have little to no impact on human health and daily life. However, some certain groups of people may need to be aware that it is best not to release pigeons during geomagnetic storms, because pigeons navigate through geomagnetic fields and are very affected by magnetic fields.
Auroras – a "by-product" of geomagnetic storms
The aurora is actually a visualization of geomagnetic storms. Aurora is a natural phenomenon that can be seen with the naked eye on the ground and is caused by the interaction of the solar wind with the magnetosphere.
After the coronal material carries the energy of the sun and meets the earth, part of it will enter the poles with the earth's magnetic field and collide with the atmosphere at a height of 100 to 400 kilometers above the ground.
Reminder
Occurrence of geomagnetic storms
Impact on our daily lives
very little
So if the guys are late
Poor sleep, lack of energy, and lightheadedness
Don't look for geomagnetic storms to "blame"!
Adjust your routine and relax!
