The strongest magnetic storm of 2026 hits Earth today

A moderate-to-strong geomagnetic storm, classified as G2 to G3, is expected today, according to astronomers at the Laboratory of X-Ray Astronomy of the Sun.
The forecast follows confirmation that a plasma cloud from an M-class solar flare on March 16 is approaching Earth.
Understanding storm intensity
Geomagnetic storms are measured on a five-level scale. A G1 storm is considered minor, G2 is moderate, and G3 is strong. Higher-level storms can disrupt communications, navigation systems, and power infrastructure.
Potential health effects
Experts note that people who are sensitive to changes in weather or geomagnetic conditions may experience discomfort during such events. Those with chronic health conditions may see symptoms worsen. They should closely monitor their health and take precautions if necessary.
