据美国宇航局（NASA）公告，太阳近日发出了强烈的 X 级太阳耀斑，干扰了无线电通信。本次耀斑活动是自 2017 年 9 月以来最强的太阳耀斑，太阳物理学家将其分为三类，C 类最弱，M 类中等，X 类最强。美国国家海洋和大气管理局（NOAA）称这次活动为“有史以来最大的太阳无线电事件之一”，将带来严重的无线电通信干扰。虽然本次太阳耀斑活动产生的 CME 不是直接针对地球，但对地球依然有影响。相关影响可能会在 12 月 17 日出现。

A recent announcement from NASA stated that the sun has emitted a strong X-class solar flare, disrupting radio communications. This solar flare event is the strongest since September 2017, and has been classified as a Category X flare by solar physicists. The National Oceanic and Atmospheric Administration (NOAA) stated that this event is one of the largest ever seen in terms of solar radio communication and will bring severe disruption to radio communications. Although this solar flare event was not directly aimed at Earth, it will still have an impact on the planet. The relevant effects are expected to appear on December 17th.
