Topline
Some states along the Canadian border are expected to see the northern lights on Thursday night, as the lasting effects of a geomagnetic storm may allow more observers to see the phenomenon, according to the National Oceanic and Atmospheric Administration.
Key Facts
The NOAA forecast a Kp index of three on a scale of nine for Thursday night, meaning there will be “more auroral activity” that “can be quite pleasing to look at” for those in the right areas.
Thursday’s view line—marking a minimal opportunity to see the phenomenon—could be pulled further south to more states, as the NOAA expects the Kp index to increase above four as geomagnetic storm conditions from Wednesday continue.
Similar auroral activity is expected on Friday and Saturday, with a forecasted Kp index of about three for either day, according to NOAA’s three-day forecast.

Where Will The Northern Lights Be Visible?
Most of Alaska will have a chance to see the northern lights, while parts of northeastern Washington, northern Idaho, northern Montana, North Dakota, northern Minnesota, northern Wisconsin and Upper Michigan have a lower likelihood of viewing auroral activity. (See view line below.)
What’s The Best Way To See The Northern Lights?
The northern lights are best seen between 10 p.m. and 2 a.m. local time, according to NOAA, which recommends traveling to a high vantage point away from light pollution.
What’s The Best Way To Photograph The Northern Lights?
National Geographic recommends using wide-angle lenses, an aperture or F-stop of four or less and a focus set to the farthest possible setting. If using a smartphone, turning on night mode and disabling flash is recommended.
Key Background
The strongest northern lights display in at least the last 500 years occurred in 2024, after NASA said activity on the sun’s surface achieved a “solar maximum.” Electrons from solar events like solar flares or coronal mass ejections interact 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. A peak in solar activity is expected to persist into early 2026, according to NASA.
