A massive Coronal Mass Ejection (CME) is expected to impact Earth, potentially causing a geomagnetic storm. The CME, which originated from the sun, is forecasted to reach Earth’s magnetic field tonight.

According to the National Weather Service’s Space Weather Prediction Center, the storm will be classified as G4, indicating a severe geomagnetic storm. This could lead to visible aurora displays in 24 states across the US.

The Aurora Service Project has issued a Geomagnetic Storm Watch for January 20th, warning of potentially hazardous space weather conditions. The National Weather Service’s forecast models indicate that the storm will be strongest around midnight UTC, with the most intense activity expected in the Northern Hemisphere.

Residents in areas where the aurora is visible are advised to check local news and weather reports for updates on viewing conditions. The visibility of the northern lights can vary depending on cloud cover, moon phase, and other atmospheric factors.

The Space Weather Prediction Center will continue to monitor the situation and provide updates as necessary.
