Northern Lights Expected in 10 States After Geomagnetic Storms

WASHINGTON — The northern lights, or aurora borealis, could be visible across ten states in the northern United States tonight due to geomagnetic storms, according to the National Oceanic and Atmospheric Administration (NOAA).

Forecasters predict a Kp index of four on a scale of nine for Wednesday night, making the northern lights more vibrant and noticeable for those in ideal viewing locations. Previously, a Kp index of five was recorded on Tuesday night, suggesting that states like Wyoming, Iowa, New York, Vermont, and New Hampshire had moments to glimpse the aurora.

NOAA estimates similar auroral displays may continue through Friday, with a forecasted Kp index near three for those two days. This geomagnetic activity is likely to bring minor to moderate radio blackouts that could affect high-frequency communications, though any significant impact is deemed unlikely.

While Alaska and northern Canada stand the best chance for visibility, regions like northeastern Washington, northern Idaho, Montana, North Dakota, northern Minnesota, and Upper Michigan also have potential for sightings. Areas in South Dakota, Wisconsin, and Maine are less likely to experience the phenomenon.

For the best viewing experience, experts recommend finding a high, north-facing vantage point away from city lights, especially between 10 p.m. and 2 a.m. local time. Simple cameras or smartphones with night mode settings can capture the stunning visuals, provided they are set correctly.

The recent opportunity to see the northern lights results from the sun reaching a “solar maximum” in October 2023, which increases solar activity and leads to more frequent and farther-reaching auroral displays. As electrons from solar events interact with the atmosphere, they create the striking light shows.

A recent NOAA tip emphasizes that active geomagnetic fields enhance aurora brightness and visibility beyond the polar regions, indicative that skywatchers might witness a spectacular display tonight.
