Overview
- NOAA forecasts at least G1 geomagnetic storm conditions from Thursday night into Friday, with potential peaks near Kp 5.
- The disturbance stems from an X8.3-class flare on Feb. 1 that launched a CME expected to graze Earth’s magnetic field.
- Auroras could be visible low on the northern horizon across parts of Alaska, Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan and Maine.
- Satellites recorded an additional X4.2 flare on Feb. 4, raising the chance of continued activity through the weekend.
- Best viewing is after dark from dark-sky locations facing north, with real-time checks advised via NOAA’s 30-minute aurora forecast and SpaceWeatherLive.
