Core Viewpoint - The article discusses the occurrence of an X1.9-class solar flare from solar activity region 14341, marking the first X-class flare of 2026, which led to significant geomagnetic storms on Earth starting January 20, 2026 [1][9]. Group 1: Solar Activity - The X1.9-class solar flare occurred on January 19, 2026, at 2:09 AM Beijing time [1][9]. - Following the solar flare, geomagnetic storms began on January 20, 2026, with a total of 6 hours of severe geomagnetic storms and 6 hours of moderate geomagnetic storms reported by 8 PM the same day [1][9]. Group 2: Geomagnetic Effects - The Fengyun-3E satellite detected the geomagnetic activity, showing a rapid decline in geomagnetic index values as the storm commenced [3][11]. - The Fengyun-3H satellite captured images of auroras in the Northern Hemisphere, visually indicating the regions affected by the auroras [4][15]. Group 3: Impacts of Geomagnetic Storms - Geomagnetic storms, while not harmful to human health, can affect aircraft and satellite operations, potentially causing satellites to experience altitude decreases due to atmospheric drag and increasing positioning errors in satellite navigation systems [8][17]. - Strong geomagnetic activity may significantly impact animal migration and navigation abilities, particularly for species like homing pigeons that rely on solar and geomagnetic cues [8][17].
