US EditionSevere solar storms could hit Earth and trigger auroras, space forecasters say
A highly active sunspot cluster is driving intense solar flares and coronal mass ejections with a 35% chance of X-class flares, threatening geomagnetic storms and auroras.
- A coronal mass ejection from the Sun is expected to reach Earth on November 11 and 12, potentially creating a colorful northern lights display visible from many northern U.S. states.
- The CMEs erupted from the Sun on November 9 and 10, with the second CME arriving shortly after the first on November 12.
- The National Oceanic and Atmospheric Administration issued a geomagnetic storm watch, with a G2 watch for November 11 and a G3 watch for November 12.

By Ashley Strickland, CNN. Dazzling auroras dazzled skywatchers Tuesday night, even in southern US states like Florida, where they rarely appear, and more displays like these are expected again Wednesday as solar storms generated by the Sun continue to reach Earth. Strong geomagnetic storm conditions — fueled by intense solar flares — are underway, the National Weather Service's Space Weather Prediction Center reported. Currently classified as G…
We’re Not Alone in Space Weather Chaos
The sun’s strong blasts that have erupted since Sunday have made themselves felt here on Earth. Our star has released three large blobs of plasma and magnetic field, which resemble big chunks of twisted rope, known as coronal mass ejections. The sun spits these CMEs out at more than 1 million miles per hour, and they commonly follow solar flares—eruptions of radiation from the sun. Nautilus Members enjoy an ad-free experience.
