Northern Lights Alert: Major Geomagnetic Storm Peaks Tonight, Auroras Expected Across Midwest

A Geomagnetic Storm Watch has been issued for late Monday, September 1st, extending into early Tuesday, September 2nd, signaling a high probability of spectacular Northern Lights displays across Michigan and a wide swath of the U.S. and Canada. This significant space weather event is the result of a “full-halo” coronal mass ejection (CME) observed on August 30th, which is now arriving at Earth.
Forecasters from the NOAA/NWS Space Weather Prediction Center anticipate the geomagnetic storm could intensify from G-2 (medium) levels on Monday evening to G-3 (strong) overnight, with a possibility of reaching G-4 levels. While such powerful storms can potentially disrupt satellites and power grids, they are also responsible for creating breathtaking auroras. Residents in states bordering Canada and across the lower Midwest should prepare for a rare opportunity to witness the vibrant green and purple waves of the Aurora Borealis. The full-halo nature of the CME indicates a direct hit, increasing confidence in Earth arrival and the potential for a strong, widespread light show tonight.
