Northern Lights Forecast: These 10 States May See Aurora Borealis Tonight Amid ‘Moderate’ Geomagnetic Storm – Forbes
Some states along the Canadian border may be able to see aurora borealis on Thursday, as high-speed winds from a spot on the sun’s surface could impact the Earth’s magnetic field, according to the National Oceanic and Atmospheric Administration.The aurora borealis fills the sky with pink and blue waves of color over a farmhouse in Mercer, … [+] Maine.NOAA forecast a Kp index of four on a scale of nine for Thursday, meaning the northern lights will be more active and be “quite pleasing to look at” for those in the right areas.The agency said a coronal hole high-speed stream—winds from a cooler, less dense area on the sun’s surface—will likely result in a geomagnetic storm later Thursday, an event that could disturb Earth’s magnetic field and pull the northern lights further south, according to NOAA’s three-day forecast.Thursday night’s forecast is expected to upgrade to a Kp index of six, NOAA said, indicating auroral activity will move further from the poles and become “quite bright and active.”Get Forbes Breaking News Text Alerts: We’re launching text message alerts so you’ll always know the biggest stories shaping the day’s headlines.

Areas in northeastern Washington, northern Montana, North Dakota, northern Minnesota and Upper Michigan will have a low likelihood, while parts of northern Idaho, South Dakota, Wisconsin and Maine have an even lower chance.

If using a smartphone, it’s recommended to turn on night mode and disable flash.Electrons from solar events like solar flares and coronal mass ejections intersect with molecules and atoms of nitrogen and oxygen in the Earth’s atmosphere, causing them to become “excited” before producing the colorful displays of aurora borealis. Activity on the sun’s surface reached a “solar maximum” in October 2024, marking an increase in solar events that will likely persist into early 2026, according to NASA. Aurora borealis displays achieved a 500-year peak in 2024, the agency said, as the strongest geomagnetic storm in the last two decades affected Earth last May, pulling the northern lights as far south as Texas and northern Florida.Northern Lights Displays Hit A 500-Year Peak In 2024—Here’s Where You Could Catch Aurora Borealis In 2025 (Forbes)One Community.
