The aurora borealis could be visible as far south as northern California and Alabama if skies are clear, according to AccuWeather. The current Space Weather Prediction Center’s “viewing line” runs through New Jersey roughly along the I-80 corridor.

Solar radiation storm alerts are active! Discover how this S4-level event triggers the Northern Lights tonight and its impact on Earth.

For those with clear skies in the northern portion of the U.S., northern lights are possible tonight!

“‘An S4 severe solar radiation storm is now in progress this is the largest solar radiation storm in over 20 years,” the Space Weather Prediction Center announced in a public message, pinpointing a moment when the most extreme effects were occurring in a way that was invisible to anyone on the surface.

The NOAA Space Weather Prediction Center has confirmed that severe G4 geomagnetic storm conditions have already been reached following the impact of a coronal mass ejection striking Earth. Simultaneously,

A geomagnetic storm occurs when high-energy plasma and magnetic fields ejected from the sun interact with Earth's magnetic field.

The northern lights may not have been as bright as you expected, but Earth’s atmosphere was still highly active.

A powerful solar eruption is expected to hit Earth soon, according to a forecast from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center. A coronal mass ejection -- a massive burst of solar material and magnetic field ...
