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 on Earth, resulting in beautiful auroras in various regions of China [2][5]. Group 1: Solar Activity and Geomagnetic Storms - On January 19, 2026, at 2:09 AM Beijing time, sunspot 14341 erupted with an X1.9-class flare, the first of its kind in 2026 [2]. - Following the flare, geomagnetic storms began on January 20, 2026, at 2:00 AM, with reports of 6 hours of severe geomagnetic storms and 6 hours of moderate storms, which are still ongoing [2]. Group 2: Effects of Geomagnetic Storms - The geomagnetic storms have led to the appearance of stunning auroras in northern China, particularly in the Greater Khingan Range of Heilongjiang province [7]. - Geomagnetic storms can disrupt shortwave communication and navigation systems across most regions of China [8]. - The storms cause disturbances in the ionosphere, affecting ground communication and satellite signals, which may impact the accuracy of navigation satellite systems and the quality of mobile and satellite TV signals [10]. - Strong geomagnetic storms can increase current loads on power transmission systems, potentially damaging transformers and other grid facilities, leading to power outages [11]. 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 [12]. - However, strong geomagnetic activity may affect animal migration and navigation abilities, particularly for birds that rely on solar and geomagnetic navigation [12].
