Northern Lights Could Dazzle U.S. This Weekend, NOAA Forecasts Geomagnetic Activity

A NOAA‑issued G1 geomagnetic storm watch due to a high‑speed solar wind could bring the Northern Lights as far south as the U.S. border this weekend, with the best displays in northern states and parts of Canada. For optimal viewing, seek dark, north‑facing spots away from city lights between 10 p.m. and 2 a.m.; the near‑90% illuminated moon may wash out faint auroras, so long‑exposure photography can help capture them.

Solar storm lights up auroras from Europe to Southern California, 23-year radiation record broken

A powerful solar radiation storm triggered by an X-class solar flare and a CME struck Earth, producing widespread auroras across Europe and parts of North America, with sightings as far south as Southern California. The storm peaked at G4 (severe) on the geomagnetic scale per NOAA’s SWPC. While dramatic, it wasn’t the strongest in two decades (the 2024 Mother’s Day event held that distinction), but it did set a 23-year record for solar-radiation storms.
