A strong G4 geomagnetic storm has been confirmed by GISTDA following an X5.1 solar flare from the Sun on November 11, 2025. The storm poses risks to global communication and power infrastructure, although Thailand is not directly affected due to its geographical position. Sectors worldwide, including satellite, aviation, and energy industries, are urged to remain vigilant.

 

The Geo-Informatics and Space Technology Development Agency (GISTDA) reported the occurrence of this potent solar event, known as a coronal mass ejection (CME), reaching Earth between November 11-12. This large-scale solar activity, analyzed with the JASPER space weather system, exceeded previous predictions and initiated the severe geomagnetic storm.

 

The storm's global implications include potential disruptions to satellite communications, high-frequency radio signals, and challenges in directional control and orbital positioning. Auroras from the storm could be seen as far south as 45° magnetic latitude. Additionally, induced electric currents may impact oil and gas pipelines.

 

Thailand remains secure from direct storm effects, thanks to its lower latitude and magnetic protection, as outlined by GISTDA. Nonetheless, local industries relying on satellite communication, aviation, and energy systems have been advised to watch developments closely.

 

GISTDA continues to monitor the situation, with plans to issue timely updates if the conditions evolve. The agency's use of NOAA's G-scale aids in understanding storm severity, where G4 indicates significant risk to technology and electricity systems, in contrast to the rare and more devastating G5 storms, reported The Nation.

 

Key Takeaways

• A G4 geomagnetic storm from an X5.1 solar flare is confirmed.
• Global sectors are on alert for communication and energy impacts.
• Thailand remains unaffected but is advised to monitor the situation.

What ??

All it takes is for some big solar flare/storm to hit at just the right time, like the Carrington Event or some nefarious actor to release and EM pulse in the atmosphere, and it's poof, bye bye smart phones and internet. How are you going to do anything when we are relying on just one thing to do everything? You will not be able to pay for anything or get any services... bet you'll wish there was still cash around and all the idiots didn't just race like lemmings of the cliff for a digital and cashless society.

All depends on if the lazy governments get round to hardening the grid and protecting capacitors and transformers from such disruptions... which they haven't yet and they are not quick to replace. Unfortunately, as democratic government are only around for the short-term (like 4-5 years), then often neglect longer term problems and just kick it into the long grass for someone else to deal with later... very short-sighted approach.

We can hope it will bankrupt Elon...
