According to the "Space Weather" WeChat *** news, at 06:34 Beijing time on February 23, 2024 (22:34 UTC on February 22, 2024), the active area 13590 located at 17 degrees north latitude and 26 degrees east longitude on the surface of the sun erupted x6A magnitude 3 flare, the largest in the current 25th solar cycle, and breaking the record for flare eruptions since September 10, 2017.

The spikes of the three curves correspond to the three X-magnitude flare processes.
From 07:07 on February 22 to 06:34 on February 23, three X-class flares broke out in less than 24 hours, and they were still in the same solar activity area, everyone can't help but wonder, why is this activity area numbered 13590 so active? The main reason for this is that the area is home to a large amount of solar energy, which manifests itself in the form of a noticeably large sunspot. Once the reconnection and rupture occurs, the original fragile equilibrium will be broken, and then there will be a rapid release of energy, that is, an explosion.
The type of flare activity is a peak-type constrained flare, which refers to the rapid up-thrust of X-ray intensity during the flare outburst and the rapid decline of the peak back to the background level. The so-called restraint corresponds to the fact that there was no eruption of a large amount of coronal material after the flare eruption, so friends who are looking forward to seeing the aurora in China will continue to wait patiently.

According to the judgment of the National Space Weather Monitoring and Warning Center, the area of the active area 13590 is still large after three major eruptions, and the magnetic field structure is a complex type of δ, and there is still a possibility of m-level or even stronger flares in the future. In terms of geomagnetism, with the combined influence of the gradual shift of the solar coronal hole to the Earth and the CME activity on the 21st, geomagnetic activity or even small geomagnetic storms may occur on the 25th.
