Overview
- NOAA forecasts G1 geomagnetic activity with a chance of G2 from Oct. 28–29, with Kp readings around 5 Tuesday night and near 4 Wednesday.
- Latest viewlines place aurora potential across northern North America, including Alaska and up to 14 U.S. states such as parts of Washington, Idaho, Montana, the Dakotas, Minnesota, Wisconsin, Michigan, Iowa, Wyoming, New York, Vermont, New Hampshire and Maine.
- The UK Met Office says visible aurora is possible in northern Scotland, with low‑confidence glimpses as far south as northern England or Northern Ireland.
- Confidence remains limited due to complex CME activity earlier in the week, so observers are urged to watch real‑time Bz and Kp data and NOAA’s 30‑minute aurora model.
- Best chances come under clear, dark skies with a north‑facing view between about 10 p.m. and 2 a.m., and light pollution or cloud cover can quickly erase visibility.
