Get ready for an extraordinary celestial display! A fresh forecast from the National Oceanic and Atmospheric Administration (NOAA) indicates that a "severe" geomagnetic storm is on the horizon, promising spectacular views of the northern lights, also known as the aurora borealis.

On Thursday, October 10, and Friday, October 11, the forecast has been upgraded to a G4 (Severe) geomagnetic storm, which could allow viewers to catch the aurora across much of the northern United States. Areas as far south as Alabama and northern California may experience this stunning natural phenomenon, making this a rare opportunity for many.

Which States Are Affected?

Regions where the northern lights may be visible include:

- The Northern States: Montana, North Dakota, Minnesota, and Wisconsin.

- Central and Southern States: Illinois, Indiana, and parts of northern California and Alabama.

This warning echoes prior alerts, such as the one before the May 10 solar superstorm, which turned out to be the most powerful display of auroras in centuries. While the severity of geomagnetic storms can fluctuate, this G4 alert, though exciting, could nevertheless devolve to a weaker G3—a phenomenon not to be missed if you’re in the right location.

Understanding Geomagnetic Storm Classes:

- G2 (Minor): Visible as far south as New York and Idaho.

- G3 (Moderate): Sightings can reach as far south as Illinois and Oregon.

- G4 (Severe): Viewable as far south as Alabama and northern California.

- G5 (Extreme): Potentially visible in Florida and southern Texas.
