The reporter learned from the Purple Mountain Observatory of the Chinese Academy of Sciences that my country's "Kuafu-1" satellite successfully recorded the largest flare so far in the 25th solar cycle. This is an X5.0-level flare that appeared on January 1, 2024, Beijing time. The solar flare was accompanied by a coronal mass ejection, which once again set a new record for the largest flare in the 25th solar activity week.

"Kuafu-1" is my country's first comprehensive solar exploration satellite. It was launched in October 2022. The three payloads of the "Kuafu-1" satellite successfully tracked and recorded this explosion, which will provide solar physicists with Brings information about accelerating high-energy electrons. By comprehensively utilizing the observation data of the "Kuafu-1" satellite and combining it with multi-band data provided by relevant domestic and foreign observation equipment, researchers will further conduct scientific research on this X5.0-class flare in the future.

Solar activity cycle and its latest predictions

It is understood that the 25th week of solar activity is about to enter its peak period. With the help of "Kuafu-1", the "eye in space", the scientific research team will continue to record and study more solar explosions.
