Solar storms may cause dim northern lights across fringes of the northern United States over the weekend as forecasters monitor for possible disruptions to power and communications.
The sun's magnetic field is currently at the peak of its 11-year cycle, making solar storms and northern lights more frequent. The sun emitted two strong flares this week, including one Thursday that was the biggest since 2017.

Faint auroras may be visible as far south as South Dakota, Iowa and New York, but the storms could still intensify or weaken over the weekend.
"There's still a fair amount of uncertainty," Erica Grow Cei, spokesperson for the U.S. National Oceanic and Atmospheric Administration, said Friday.
Unusually strong solar storms in May produced jaw-dropping aurora displays across the Northern Hemisphere. This week's storms featured fewer ejections of the high-energy plasma that can drive a light show, according to NOAA.
