A Powerful Solar Flare and Its Impact: Thailand's Safety Amidst a Geomagnetic Storm
On November 11, 2025, a solar flare of unprecedented strength erupted from the Sun, sending shockwaves across the globe. The Geo-Informatics and Space Technology Development Agency (GISTDA) reported that this X5.1-class solar flare unleashed a massive coronal mass ejection (CME) towards Earth, resulting in a severe geomagnetic storm of G4 intensity—the strongest in years.
The storm's impact was far-reaching, with potential disruptions to satellite communication, directional control, and orbital adjustments. High-frequency (HF) radio signals could experience temporary interference, and induced electric currents might affect pipelines transporting oil and gas. However, Thailand, located at a low magnetic latitude, was fortunate to be shielded from the storm's direct impact.
Despite being unaffected, Thailand's authorities advised sectors involving satellite communication, aviation, and energy systems to remain vigilant and closely monitor the situation. GISTDA committed to tracking the geomagnetic storm closely and providing timely updates as conditions evolve, ensuring the public's safety and preparedness.
