M5.1 Solar Flare Triggers Radio Blackout on Earth #SolarStorm A powerful M5.1 solar flare erupted from the Sun’s Earth-facing side, causing a moderate R2 radio blackout across parts of the sunlit side of our planet. ☀️🌍 The flare originated from an unnumbered active region near AR 4323, disrupting high-frequency (HF) radio communications used in aviation, maritime operations, and emergency services. Although the flare has subsided, scientists at NOAA are closely monitoring the active region for
