Solar Storm Hits Earth: Northern Lights Could Be Visible Across These U.S. States Tonight!

Skywatchers in parts of the northern U.S. could glimpse the Northern Lights tonight as a solar storm approaches Earth. A coronal mass ejection (CME) from a solar eruption on 1 March is set to interact with Earth’s magnetic field between 4 and 5 March. This could potentially trigger a geomagnetic storm and auroral displays.

Where And When To See The Northern Lights

According to the National Oceanic and Atmospheric Administration (NOAA), the storm is expected to peak between 7:00 p.m. and 10:00 p.m. EST on 4 March (00:00-03:00 GMT on 5 March).

The strongest auroral activity will be in Alaska and Canada. However, the northernmost parts of the U.S. may also get a view. If conditions strengthen to a G2-level storm, auroras could be visible as far south as New York and Idaho.

The storm is expected to taper off throughout 5 March, with activity returning to normal by 6 March.

What Causes The Northern Lights?

The Aurora Borealis occurs when charged particles from the sun interact with Earth’s magnetic field, creating colourful displays in the sky. Geomagnetic storms, like the one predicted tonight, enhance auroral activity, making them visible at lower latitudes than usual.

NOAA classifies geomagnetic storms using a G-scale, ranging from G1 (minor) to G5 (extreme). The current forecast predicts a Kp index of 5, indicating a minor G1 storm, but some forecasts suggest it could reach G2 levels, improving visibility further south.

Best Viewing Tips

For the best chance to see the northern lights:

• Find a dark location away from city lights.
• Check the weather forecast—clear skies are essential.
• Look north for the best view.
• Try between 10 p.m. and 2 a.m. when activity is usually strongest.
• Use a camera with a long exposure—auroras can be faint to the naked eye but appear stronger in photos.

More Aurora Activity In 2025?

2024 was an exceptionally strong year for auroras, with one of the most powerful geomagnetic storms in 20 years occurring in May. This trend is expected to continue through 2025, as the sun remains in a period of high activity known as solar maximum — the peak of its 11-year cycle.
