The Northern Lights may be visible across 12 northern U.S. states and Canada as soon as it gets dark on Wednesday, Oct. 29, 2025, according to a forecast from the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC). The forecast includes a G1-rated geomagnetic storm that could see displays of aurora.
The forecast comes in the wake of visible auroras across northern latitudes in the past few nights, after a coronal mass ejection — a cloud of super-charged particles that leaves the sun and takes a few days to reach Earth — began interacting with Earth’s magnetic field, followed by fast-moving solar wind.
NOAA forecasters say the impact may be a G1-rated geomagnetic storm resulting in auroras for northern U.S. states, Canada and northern Europe.
