据NASA太阳动力学天文台消息，北京时间2023年12月31日17时55分，捕捉到一个X5.0级别的太阳耀斑。这是太阳活动周期中的第25个太阳活动周期，科学家预测此次耀斑爆发将在2025年前后达到活动高峰。耀斑产生的有害辐射无法穿过地球大气层，但当耀斑强度足够大时也会对地球产生影响，例如导致极光出现在更低的纬度、扰乱GPS和无线电通信传播，甚至在极端情况下可能导致电网故障，并对航天器和宇航员构成威胁。此外，耀斑还可能对人类健康产生一定的影响，如增加癌症风险等。

Translation: According to NASA’s Solar Dynamics Observatory, a message was received at 3:55 pm北京时间 on December 31, 2023, indicating the detection of an X5.0-level solar flare. This is the 25th solar activity cycle in the current solar cycle, and scientists predict that the flare will reach its peak around 2025. The harmful radiation emitted by the flare cannot penetrate the Earth’s atmosphere, but when the flare is powerful enough, it can also have an impact on Earth, such as causing the aurora to appear at lower latitudes, disrupting GPS and radio communication, and potentially causing power grid failures and threats to spacecraft and astronauts. In addition, flares may also have an impact on human health, such as increasing the risk of cancer.
