Northern Lights Forecasted Over Northern U.S. States Amid Minor Geomagnetic Storm

A minor geomagnetic storm is expected to make the aurora borealis visible across several northern U.S. states tonight, according to the National Oceanic and Atmospheric Administration (NOAA). The affected areas include northern Washington, northern Idaho, most of Montana, North Dakota, parts of South Dakota, and northern regions of Minnesota, Wisconsin, and Michigan. Most of Alaska is also within the viewing area.

NOAA advises that the best viewing times are between 10 p.m. and 2 a.m. local time. To enhance visibility, observers should travel northward, away from city lights, and find a location with a clear view to the north.

The current geomagnetic storm is classified as a G1 (minor) on NOAA's five-level scale. Such storms can cause minor impacts on satellites and weak power grid fluctuations, while also expanding the aurora's visibility to more southern latitudes.

Coronal mass ejections (CMEs) are significant releases of plasma from the sun that can lead to geomagnetic storms when they interact with Earth's magnetic field. The current storm is considered minor, but it still has the potential to make the northern lights visible in areas where they are not typically seen.

For those interested in photographing the aurora, experts recommend using a tripod to stabilize the camera during long exposures. A wide-angle lens with an aperture of 4.0 or lower is suggested for capturing the night sky. Smartphone cameras can also be effective, especially when the flash is turned off and night mode is enabled.
