On March 14, according to a report from the Solar Astronomy Laboratory of the Russian Space Research Institute, this is the first notable geomagnetic phenomenon in March 2026. This storm began to break out from about midnight (Moscow time) and maintained stable intensity for many consecutive hours. The cause was identified as the sudden increase in the speed of the Sun wind.
Experts say the index of this magnetic storm is maintained at G1.7, equivalent to the average level. Although the intensity is not too large, the abnormality lies in its stability and durability. Unlike the short fluctuation on March 4 before, this magnetic storm lasted for many hours, creating continuous magnetic pressure on the Earth's atmosphere.
The past year of 2025 was already recorded as the year with the strongest geomagnetic activity in a decade, with about 19% of events having intensity equivalent to or greater than this storm. However, based on data collected from the beginning of the year to date, scientists emphasize that 2026 is on track to set a new record for both the number and intensity of similar astronomical phenomena.
Close monitoring of magnetic storms is extremely important because they can disrupt radio communication systems, distort the accuracy of GPS positioning and put great pressure on high-voltage power grids. In some high-altitude areas, magnetic storms can also create beautiful auroras, but go hand in hand with the risk of disrupting electronic devices on intercontinental flights.
For humans, especially those sensitive to weather changes, prolonged magnetic storms can cause fatigue, headaches, or mild insomnia. Doctors recommend that during these times, people should limit excessive physical activity, drink plenty of water, and rest reasonably to adapt to magnetic field fluctuations.
