The strongest geomagnetic storm of 2025 is expected Friday, Nov. 7 — one of the most intense in recent years. According to preliminary data, Earth will be hit by a stream of solar plasma ejected during a series of powerful solar flares.
What are the risks?
During strong geomagnetic storms, disruptions in satellite communications, GPS systems and internet connections are possible. Power grid fluctuations and health issues among weather-sensitive individuals can also occur.
How to protect yourself
Experts recommend several practical steps:
- Minimize stress and physical activity.
- Stay hydrated and avoid coffee and alcohol.
- People with chronic cardiovascular conditions should keep essential medications on hand and avoid going out unless necessary.
- Postpone long trips and air travel if possible.
If you feel weak, dizzy or develop a headache, lie down, rest and practice deep breathing.
Strong magnetic storms can last several hours to a full day, with lingering effects felt for one to two days afterward. Scientists advise monitoring expert forecasts and paying close attention to your health during this period.
