地球出现特大地磁暴

Core Viewpoint - The article discusses the occurrence of an X1.9-class solar flare from sunspot 14341, marking the first X-class flare of 2026, which has led to significant geomagnetic storms affecting Earth and creating beautiful auroras in several regions of China [3][8]. Group 1: Solar Activity and Geomagnetic Storms - On January 19, 2026, at 2:09 AM Beijing time, a significant solar flare occurred, resulting in geomagnetic storms starting from January 20, 2026, at 2:00 AM [3]. - The geomagnetic storm has been categorized into six hours of severe geomagnetic storms and six hours of moderate geomagnetic storms, with the storm still ongoing [3]. Group 2: Effects of Geomagnetic Storms - Geomagnetic storms can disrupt shortwave communication and navigation systems across most regions of China to varying degrees [10]. - The storms can increase atmospheric particle movement, leading to greater flight resistance for spacecraft, posing risks to their safety in orbit [11]. - Strong geomagnetic storms may affect power transmission systems, increasing current loads on transmission lines and potentially damaging transformers or other grid facilities, which could result in power outages [13]. Group 3: Impact on Daily Life - The impact of geomagnetic storms on public daily life and health is minimal, and no special precautions are necessary [15]. - However, strong geomagnetic activity may affect animal migration and navigation abilities, particularly for species that rely on solar and geomagnetic navigation, such as homing pigeons [15].
