Geomagnetic Storms to Bring Northern Lights Southward This Weekend
Solar activity from recent coronal mass ejections is predicted to make auroras visible in lower latitudes across North America and Europe.
- NOAA forecasts minor geomagnetic storms on January 4 and 5, potentially making the northern lights visible as far south as northern Iowa, Maine, and Michigan.
- The auroras are tied to a series of coronal mass ejections (CMEs) that released charged particles from the Sun, disturbing Earth's magnetic field.
- Viewers in areas with clear, dark skies between 10 p.m. and 2 a.m. may have the best chance to witness the auroral displays.
- The Sun's increased activity, linked to its 11-year solar maximum cycle, is expected to enhance auroral activity through 2025.
- Experts caution that geomagnetic storms can cause minor disruptions to power grids, satellites, and navigation systems, even as they create stunning sky displays.
