Overview
- NOAA’s Space Weather Prediction Center expects a G1 geomagnetic storm overnight from Tuesday, Jan. 27, into Wednesday, Jan. 28.
- The agency’s aurora viewline points to possible low-on-the-horizon sightings across up to 11 U.S. states near the Canadian border, from Alaska to Maine.
- Observers are advised to track live data on solar-wind speed and the interplanetary magnetic field’s Bz, with a sustained southward Bz near or below -5 nT often preceding visible aurora.
- A 68% waxing gibbous moon, cloud cover, and light pollution could reduce naked-eye visibility, so darker sites with a clear northern horizon will improve chances.
- Solar activity remains elevated into 2026 following the late-2024 peak, and faint auroras may appear more clearly in long-exposure photos or smartphone Night/Pro modes.
