A significant M8.9 class solar flare erupted from the Sun on May 25, 2025, at approximately 16:18 UTC. The flare originated from active region AR4098 and is classified as one of the strongest M-class flares observed recently, reaching almost the intensity of an X-class flare.
Solar flares are categorized into classes based on their X-ray emission, ranging from A (weakest) to X (strongest). Each class represents a tenfold increase in energy. The M8.9 flare caused a moderate R2 radio blackout over the western Pacific region.
While the coronal mass ejections (CMEs) associated with this flare are not expected to impact Earth directly, scientists continue to monitor solar activity. Increased solar activity can lead to geomagnetic disturbances, potentially affecting satellite operations and radio communications.
