No Health Threat from Solar Storm in Thailand: GISTDA

The Geo-Informatics and Space Technology Development Agency (GISTDA) warns of potential technical disruptions in Thailand due to a Level G4 geomagnetic storm. Despite Thailand's low-latitude position, satellite systems, navigation, and aviation might experience signal inaccuracies. This comes after a solar flare erupted from Active Region 4341 on January 19, releasing radiation and a coronal mass ejection towards Earth.

The eruption included plasma and magnetic fields, intensified by solar wind, causing increased geomagnetic activity. Although the storm does not pose a direct threat to the public, technical impacts include accelerated altitude loss of low Earth orbit satellites and decreased GPS accuracy. Satellite operators may need to adjust orbits, and GPS-reliant tasks like surveying or drone operations could face challenges.

High-frequency aviation communications might experience intermittent outages necessitating caution among pilots and air-traffic controllers. GISTDA advises continued vigilance from involved agencies and operators. The Space Weather team will provide updates if conditions fluctuate.

Looking forward, GISTDA confirms the situation will be monitored closely, with the public reassured of no direct physical harm or electrical impact from the geomagnetic storm. The focus remains on preemptive adjustments and careful monitoring by technological and communication sectors, reported The Nation.

Key Takeaways

  • The G4 geomagnetic storm may disrupt satellite and GPS operations in Thailand.

  • Aviation communication systems might experience intermittent outages.

  • Public health and household electricity are not affected by the storm.

I'm not a rocket scientist but I though that it takes about 7 minutes for 'stuff' from the sun to hit the earth so this event would have happened already yesterday ?

It takes about 8 minutes for the electromagnetic radiation to arrive. Particulates probably take a little longer as they do not travel at light speed.

My sister lives in Plymouth, UK, and said the Northern Lights were visible on Sunday night.

Wow it would have been extraordinary to see the Aurora Borealis that far south

must be a very strong magnetic storm...or perhaps there is something going on with the earth's magnetic field...

We kind of understand that there may be effects on electronic communications and probably no effect on human health but a question that nobody asks is : How long does this solar storm last ?

Until it stops.

Don't worry you will be ok.

I am relieved by this news.

It is essentially impacting the whole planet, not just Thailand.
