Overview
- NOAA expects the CME to arrive late Jan. 2 into early Jan. 3 with unsettled to G1–G2 geomagnetic storming, a timeline echoed by the UK Met Office.
- Aurora could be visible across roughly 17–20 U.S. states, with the best odds from Alaska and the Upper Midwest to Maine and a lower chance on the northern horizon in parts of Oregon, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, New York, Vermont and New Hampshire.
- The Met Office says parts of the UK could also see activity through the weekend if skies are dark and clear.
- Viewing is most favorable between about 10 p.m. and 2 a.m. local time from dark locations with a clear northern horizon away from city lights.
- Cloud cover and the bright Wolf Supermoon may wash out faint displays, and forecasters advise checking NOAA’s 30‑minute aurora outlook, SpaceWeatherLive and dedicated apps for real‑time conditions and potential activity into Sunday.
