Overview
- NOAA’s latest outlook keeps minor geomagnetic storm conditions through Saturday night into early Sunday with Kp around 5, with a coronal mass ejection bringing a chance of brief G2 levels.
- Aurora visibility is possible along the northern horizon in parts of 14–15 U.S. states, including Washington, Idaho, Montana, Wyoming, the Dakotas, Minnesota, Iowa, Wisconsin, Michigan, New York, Vermont, New Hampshire and Maine, plus Alaska.
- Forecast maps show widespread Canadian visibility, including southern Ontario and southern British Columbia, with cities such as Toronto, Ottawa, Montreal and Victoria within the view line on Friday and Saturday nights.
- Forecasters attribute the activity to a positive‑polarity coronal hole high‑speed stream combined with solar eruptions on Sept. 4 that sent energy toward Earth.
- Best chances come from dark, north‑facing locations between roughly 10 p.m. and 2 a.m. local time, with real‑time tracking available on NOAA’s Aurora Dashboard and 30‑minute forecast tools; bright moonlight and clouds may reduce visibility.
