Sun Emits Strong Solar Flares in 2026, ISRO Monitors Potential Radio Blackouts

In early February 2026, the Sun emitted multiple powerful solar flares, including an X8.3 flare—the strongest recorded this year—originating from an expanding sunspot. These flares disrupted Earth's upper atmosphere, causing R3-level radio blackouts in parts of the South Pacific and affecting shortwave communications in Australia and New Zealand. India's space agency ISRO is monitoring over 50 satellites closely, warning of potential radio and power blackouts, with contingency plans in place. Scientists worldwide continue to track solar activity due to its impact on communication, navigation, and power systems.
