According to news released by the National Space Weather Monitoring and Warning Center of the China Meteorological Administration, at 16:30 on November 14, Beijing time, an X4.0-level flare broke out in solar active area 14274. This is the fifth X-class flare outbreak in this active area during the current rotation cycle, and as the sun rotates, it will turn out of the visible side.
Since the flare occurs during daytime in most parts of my country, changes in the ionospheric environment caused by solar radiation may have a certain impact on radio shortwave communications.
This flare process also produced a coronal mass ejection, but the area where it occurred was located to the north on the right side of the sun, so its material transfer direction was deviated from the Earth's location.
It is expected that geomagnetic storms may be brought to the earth in the future, but the intensity will not be too great. For "aurora hunters" who have just completed their continuous running and chasing the aurora feast, this time the aurora will be weaker, which is a "good opportunity" to rest.
The meteorological department predicts that the level of solar activity will be low in the next three days, and the possibility of an M-level or above flare is low.
A small geomagnetic storm may occur on the 16th and 17th. During the rest of the time, geomagnetic activity will be mainly calm to slightly disturbed. The high-energy proton flux in the geostationary orbit with an energy greater than 10 MeV will be at the background level. The daily integrated flux of high-energy electrons in the geostationary orbit with an energy greater than 2 MeV will be at a medium level.
The ionospheric weather is mainly calm.
It is understood that flares are one of the two most violent explosive phenomena in the solar atmosphere. They are caused by the rapid release of a large amount of energy in a short period of time due to the local magnetic field of the sun, including the generation of full-band radiation enhancement, material movement, particle acceleration, etc.
However, due to the protection of the Earth's atmosphere and magnetic field, its impact on people on the ground is usually limited.
