China’s Advanced Space-Based Solar Observatory (ASO-S), called Kuafu-1 in Chinese, has detected more than 100 flares of solar white light since its launch in October 2022, according to China’s Purple Mountain Observatory. Chinese Academy of Sciences.

Solar white light flares are a type of flare that exhibits increased radiation in the continuous spectrum of visible light. These eruptions typically have high energy and can have an impact on space weather, causing disruptions or interruptions in terrestrial communication, in addition to interfering with the normal functioning of spacecraft.

Before the launch of ASO-S, observation and reporting of solar white light flares was limited to about 300 cases, which represented a relatively small proportion of the total number of flare eruptions.

The satellite’s research team analyzed 205 high-energy bursts that occurred between October 2022 and May 2023. Among them, 49 white light flares were identified, resulting in a white light flare occurrence rate of 24%, which is significantly higher than previously observed data.
