• •Sunspot AR4366 is responsible for the intense solar activity.
• •The X8.3 flare caused strong radio blackouts.
• •A glancing CME impact is possible around Feb. 5.
• •More eruptions are likely as the sunspot faces Earth.

A rapidly growing sunspot, AR4366, has unleashed a series of powerful solar flares, including an intense X8.3 eruption, the strongest of 2026 so far. This prolific region has fired off at least 18 M-class and three X-class flares within 24 hours, causing radio blackouts and disrupting Earth's atmosphere. Scientists are monitoring for potential coronal mass ejections (CMEs) that could impact Earth, with a glancing blow possible around February 5th. Further eruptions are expected as the sunspot continues to rotate towards Earth, potentially increasing geomagnetic activity and aurora visibility.
