IT Home (China) – Earth's magnetic field has undergone a significant geomagnetic storm lasting 24 hours, beginning Tuesday morning. This event represents the most substantial geomagnetic activity recorded since January 20.

The disturbance was triggered by a powerful X1.3 class solar flare that erupted from the sun late Monday or early Tuesday. The resulting solar wind, a stream of charged particles, impacted Earth's magnetosphere, causing the storm. Despite its intensity, most of China was not significantly affected, likely because the flare's peak occurred during local nighttime hours.

According to China's National Space Weather Monitoring and Warning Center, solar activity is expected to remain high over the next three days, with potential for M-class or stronger flares. Coronal Mass Ejections (CMEs) may cause short-lived geomagnetic activity, possibly including minor storms, on Tuesday. Geomagnetic activity is predicted to be calm to unsettled on other days.

Minor disturbances in the ionosphere are also anticipated over the next three days. These space weather phenomena can potentially influence satellite operations, communication systems, and power grids.
