Top 5 things you need to know about this solar spectacle: geomagnetic storm lights up the sky
- What it actually is: A geomagnetic storm is a major disturbance of Earth's magnetosphere caused by a coronal mass ejection (CME) from the sun, sending charged particles hurtling toward our planet.
- The aurora forecast: This storm is producing stunning northern lights (aurora borealis) visible much farther south than usual—potentially as far as Alabama or Oregon if weather permits.
- Impact on technology: These storms can disrupt GPS signals, radio communications, and even power grids; experts warn of possible voltage alarms and transient fluctuations in electricity systems.
- How to view it safely: Look up after dark away from city lights for the best display; no special equipment is needed—just your eyes and a clear horizon.
- Duration and rarity: While minor geomagnetic storms are common, this is a strong (G3-rated) event, making it a rare treat for most latitudes that could last for several hours.
