21 US States to Witness Northern Lights Tonight
Tonight, November 11-12, residents across parts of the United States may experience a stunning display of the northern lights. This potential spectacle is due to two coronal mass ejections (CMEs) that could create heightened geomagnetic storm conditions. The National Oceanic and Atmospheric Administration (NOAA) has predicted strong geomagnetic activity, possibly reaching level G3.
Coronal Mass Ejections and Geomagnetic Storms
The first CME was launched on November 9 and is expected to reach Earth late tonight. A second CME, which erupted just yesterday, is also on its way. Furthermore, a significant third CME was released during an X5.1 solar flare, the strongest solar flare recorded in 2025. This third CME may impact Earth by November 12, with an estimated arrival time of 7 a.m. EST (1200 GMT). The NOAA has therefore issued a G4 storm watch for tomorrow.
