A geomagnetic storm triggered by a coronal mass ejection (CME) could illuminate the skies as far south as New York and Idaho tonight. The National Oceanic and Atmospheric Administration (NOAA) has issued an aurora alert, predicting a G1-class storm, with potential for G2 conditions, meaning brighter and more widespread northern lights.

What Is Causing The Northern Lights Tonight?

The event is linked to a solar eruption that occurred on March 1, sending a stream of charged particles toward Earth. As these particles collide with Earth’s magnetosphere, they create stunning auroras in the polar regions. If the storm strengthens, the auroras could extend to mid-latitudes, making them visible in unexpected locations.

The NOAA’s Space Weather Prediction Center (SWPC) has forecasted that the CME will graze Earth’s magnetic field on March 4 or 5, with a chance of enhanced auroral activity. Space weather physicist Tamitha Skov has indicated that the storm could reach G2 intensity, improving the chances of seeing the northern lights.

Where And When To See The Auroras?

The best opportunity to witness the northern lights will be between 7:00 p.m. EST and 10:00 p.m. EST (00:00-03:00 GMT) on March 5, with activity gradually decreasing throughout the night before returning to normal by March 6.

To maximize the chances of seeing the auroras, it is essential to find a dark location away from city lights, as light pollution can diminish visibility. Observers should direct their gaze toward the northern horizon, where the auroras are most likely to appear.

Impact On Technology And Communications

Geomagnetic storms create stunning auroras, its can also disrupt satellite communications, GPS signals, and power grids. During a G1 storm, these effects are typically minor, but if it escalates to G2, disruptions could become more noticeable.

High-frequency (HF) radio signals and GPS accuracy may degrade, particularly in high-latitude regions. Drone pilots and aviation navigation systems may also experience brief signal interference.

What Does This Mean For Solar Activity?

The Sun is currently approaching solar maximum, the peak of its 11-year cycle. This means solar flares, CMEs, and geomagnetic storms will become more frequent in the coming months.

Increased solar activity raises the potential for more intense auroras in unexpected locations. If this storm reaches G2 levels, it could be an early indication of more frequent auroral events throughout 2025.

How To Capture The Northern Lights?

For those hoping to photograph the auroras, using a camera with manual settings and adjusting for a long exposure can help capture the best shots. A tripod is essential to keep images stable, especially in low-light conditions.

Since aurora chasing often involves waiting in the cold, dressing in warm layers is advised to stay comfortable while watching the sky. Checking NOAA’s space weather forecast can provide real-time alerts on auroral activity and help determine the best times to step outside.

For skywatchers in New York, Idaho, and other mid-latitude regions, tonight presents a rare opportunity to witness one of nature’s most mesmerizing displays.
