NOAA: Northern Lights Possible in 10 States on Thanksgiving Night

Forecasters attribute the display to a coronal-hole high-speed solar wind producing minor G1 geomagnetic storm conditions.

Overview

  • NOAA projects aurora visibility late Wednesday into early Thursday and again Thursday night, with Kp index forecasts near 4 on both evenings.
  • Potential viewing includes parts of Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan and Maine, depending on real-time conditions.
  • Activity earlier in the week briefly reached Kp 5 with a wider U.S. footprint, but forecasts have eased to Kp 4 for Nov. 26–27.
  • Clear, dark, north-facing skies are essential, and NOAA’s 30-minute aurora outlook or apps such as My Aurora Forecast and Aurora Now can help track short-term changes.
  • The event is classified as G1 (Minor), driven by a high-speed solar wind stream from a coronal hole, with expected impacts limited mainly to enhanced aurora visibility.
