Top 5 Things You Need to Know About the Geomagnetic Storm Hitting Earth Tonight
- A powerful geomagnetic storm is forecast to reach Earth tonight, potentially disrupting GPS signals, radio communications, and satellite operations, while also delivering stunning aurora displays as far south as Alabama and Northern California.
- The storm, caused by a coronal mass ejection from the sun, is rated G3 on the NOAA space weather scale, meaning it could cause voltage irregularities in power grids and require minor satellite corrections.
- Experts advise checking your emergency kit and backup offline maps, as the storm may interfere with cell tower connectivity and precision navigation used by ride-sharing apps and delivery drones.
- The spectacular northern lights could be visible from 50 U.S. states if skies are clear, with peak visibility predicted between 10 p.m. and 2 a.m. local time—ideal for stargazers and photographers.
- To protect sensitive electronics, unplug high-value devices from wall outlets during the storm's peak hours to reduce risk from induced currents, and avoid booking flights over polar routes tonight due to increased radiation exposure.
