URGENT UPDATE: A Severe Geomagnetic Storm Watch has just been issued for the United States, set to peak on November 12, 2025. The NOAA’s Space Weather Prediction Center (SWPC) reports that multiple Coronal Mass Ejections (CMEs) are barreling towards Earth, with the strongest detected peaking at 5:00 a.m. today.
This unprecedented activity from the sun poses a dual threat. While there’s potential for stunning northern lights visible as far south as Alabama and northern California, there is also a significant risk of disruption to critical technology infrastructure across the U.S.
The SWPC forecasts a Kp Index of 8 on Wednesday afternoon, indicating a strong geomagnetic storm. Following the peak, the Kp Index is expected to remain elevated at 7 through the night. This level of geomagnetic storm, classified as G4, is rare, with only four such watches issued during the current solar cycle.
Mike Murray, Planetarium Manager and Astronomer at the Delta College Planetarium, emphasizes the importance of understanding the implications of these storms. “The Kp index is a numerical scale (0-9) that measures the strength of geomagnetic storms, while the G-scale (G1-G5) provides a user-friendly description of the storm’s effects on technology and infrastructure.”
Residents in areas like Michigan may have a chance to witness this celestial phenomenon. Meteorologists anticipate a possible break in cloud cover on Wednesday evening, allowing for optimal viewing conditions. Enthusiasts are encouraged to find dark locations with clear views to the north.
The SWPC reminds the public that while the dazzling display of the northern lights is a highlight, the potential for technological disruptions cannot be overlooked. As these storms can affect satellites, communication systems, and power grids, staying informed and prepared is essential.
As the clock ticks down to Wednesday afternoon, get ready for what could be an awe-inspiring night filled with northern lights. Be sure to share this news with friends and family to ensure everyone is aware of this exciting and potentially disruptive event.
Stay tuned for further updates as this situation develops.
