Northern Lights Set to Dazzle Grand Forks Residents
A pale green glow could ripple over the Greenway after dusk this week, if skies cooperate and the Sun’s latest eruptions arrive on schedule. Space weather forecasters are tracking multiple solar outbursts that could spark strong geomagnetic storms and push auroras as far south as North Dakota, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.
NOAA analysts say the current solar activity includes coronal mass ejections—vast clouds of magnetized plasma—that can disturb Earth’s magnetic field when they arrive one to three days after launch. “The most severe storms are associated with coronal mass ejections (CMEs),” the agency notes in its geomagnetic storm overview, which also outlines timelines and intensity scales from G1 (Minor) to G5 (Extreme) NOAA SWPC. NASA’s heliophysics team adds that auroras brighten and spread equatorward during stronger storms, making sightings likelier in the northern tier of the U.S. NASA Earth Observatory.
Why it matters reaches beyond a vivid sky. Severe solar storms can induce small power grid currents, degrade GPS accuracy, and disrupt high-frequency radio communications, according to NOAA SWPC. For Grand Forks, that means a potential light show—and brief, manageable hiccups for technologies many residents and UND researchers rely on.
Understanding Solar Storms and Auroras
At a basic level, the Sun sometimes hurls bursts of energy and particles toward Earth. When those charged particles reach our planet, Earth’s magnetic field funnels them toward the poles; collisions with atmospheric gases release light, creating the northern lights, NASA explains NASA Earth Observatory. NOAA describes a geomagnetic storm as “a major disturbance of Earth’s magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth” NOAA SWPC.
UND faculty who study space weather note that storm strength and viewing latitude go hand in hand. In plain terms: bigger storms push the auroral oval farther south, increasing visibility for cities like Grand Forks. For background on ongoing research and public outreach in the field, UND’s Department of Physics & Astrophysics and the John D. Odegard School’s Space Studies program publish updates and host talks tied to heliophysics and Earth–Sun interactions UND Physics & Astrophysics | UND Space Studies.
Historically, North Dakota has enjoyed memorable displays during stronger events. During the intense geomagnetic storm in May 2024 (rated G5/Extreme), auroras were visible well into the Lower 48, according to NOAA’s event summaries NOAA SWPC News. At Grand Forks’ latitude (~48°N), skywatchers typically have a good chance when the Kp index—a global measure of geomagnetic activity—reaches 6 or higher, the University of Alaska Fairbanks’ Geophysical Institute advises UAF GI Aurora Forecast.
Preparing for the Light Show
The formula for success is simple: dark skies, a clear northern horizon, and patience. In town, the Greenway’s darker stretches north of downtown and viewpoints near Riverside and Lincoln Drive Parks offer quick access; outside the city, Turtle River State Park and rural roads west of I-29 reduce light pollution (check park hours and road conditions before you go) The Greenway | Turtle River State Park. Aim for 10 p.m. to 2 a.m., when activity often peaks and the sky is darkest.
Cloud cover can make or break the night. Before heading out, check the latest hourly sky and cloud forecasts from the National Weather Service in Grand Forks and adjust plans accordingly NWS Grand Forks. If conditions improve near dawn, a quick scan to the north can still pay off—auroras sometimes surge late.
A few practical tips go a long way: dress in layers, bring a red-light flashlight to preserve night vision, and park well off roadways with hazard lights off to avoid glare. Photographers should try wide lenses, high ISO, and 1–5 second exposures; most newer smartphones’ night modes can capture color even when the eye sees faint gray. Respect private property and posted hours, and consider carpooling from UND or downtown to reduce traffic in rural areas.
Expert Perspectives and Community Voices
Local scientists emphasize both the beauty and utility of a bright aurora. UND researchers point out that these storms are “living laboratories,” offering data on how the Sun energizes near-Earth space and how that energy couples into the upper atmosphere—work that underpins satellite operations, aviation planning, and power grid resilience UND Space Studies.
Community groups often turn a forecast into a teachable moment. Watch UND’s newsroom and department calendars for short-notice skywatch announcements or talks when conditions line up; pop-up gatherings sometimes form on campus lawns or along the Greenway when the oval dips south UND Newsroom. If you’re new to aurora viewing, veteran local photographers and astronomy enthusiasts frequently share real-time tips and images on regional social feeds once activity kicks up.
Keeping an Eye on the Sky
Beyond the spectacle, elevated geomagnetic activity can bend radio signals, cause fleeting GPS position errors, and add drag to low‑Earth‑orbit satellites, according to NOAA SWPC. Those effects are typically mild and short-lived, but they can matter for UND’s aviation training and for operations at Grand Forks Air Force Base that depend on precise timing and HF communications. Residents can monitor any public advisories through the base’s Public Affairs channels and city alerts Grand Forks AFB | City of Grand Forks.

What to Watch
Forecasters will refine arrival times and storm strength as fresh solar wind data streams in; check NOAA’s updates each afternoon and evening for the latest probabilities and Kp outlook. If a strong watch is issued, expect best viewing between 10 p.m. and 2 a.m. with the darkest skies away from city lights. We’ll monitor NOAA and NWS feeds and flag any UND or community viewing events if the auroral oval dips over the Red River Valley.
