Aurora borealis, also known as the northern lights, will be visible across parts of the US on Sunday, according to the National Oceanic and Atmospheric Administration (NOAA). The aurora is expected to appear brighter than usual due to a solar maximum, which increases the number of solar flares that lead to increased visibility.
The northern lights are predicted to have a Kp index of three, indicating it will be more visible and “become brighter” as it moves away from the poles. This means people in areas where it can be viewed will see an improved display when the index is between three and five.
In Alaska, the northern lights will be most visible on Sunday, while parts of Idaho, Michigan, Minnesota, Montana, North Dakota, Washington, and Wisconsin are also within the viewline. The best time to see the northern lights is between 10 pm and 2 am, and observers should look for a spot pointing north with minimal city light pollution.
To capture good photos of the northern lights, experts recommend using a tripod, a wide-angle lens, and setting an aperture or F-stop of four or less. iPhone and smartphone users can also use a tripod to stabilize their camera, turning off flash and using night mode if possible.
The increased visibility of the northern lights is due to a solar maximum in the sun’s 11-year cycle, which is expected to continue through 2025 and into 2026, according to NASA.
