Key Takeaways
- Rare Event: Northern Lights may be visible across multiple northern US states.
- Best Viewing: Tuesday and Wednesday nights (October 28-29).
- Prime Locations: 14 states, especially along the US-Canada border.
A rare display of the Northern Lights, or Aurora Borealis, is expected to be visible across multiple northern US states this week, according to NOAA’s Space Weather Prediction Center. The celestial phenomenon could illuminate skies as far south as the northern contiguous US from Tuesday night, October 28, through Wednesday night, October 29.
What’s Causing This Aurora Activity?
Increased geomagnetic activity, driven by a large coronal hole on the Sun and the effects of a weak coronal mass ejection that reached Earth on October 27, is enhancing aurora potential. The Kp index, which measures geomagnetic activity, is forecast to fluctuate between active and storm levels. NOAA predicts minor (G1) geomagnetic storms with a chance of moderate (G2) activity if solar winds intensify.
Where Can You See the Northern Lights in the US?
According to NOAA’s aurora forecast map, 14 states fall within or near the viewing zone:
- Alaska
- Montana
- North Dakota
- Minnesota
- Wisconsin
- Washington
- Idaho
- South Dakota
- Michigan
- Vermont
- New Hampshire
- Wyoming
- Iowa
- New York
The strongest visibility is expected in northern Alaska, while regions along the US-Canadian border—particularly Montana, North Dakota, and Minnesota—offer the best viewing opportunities in the lower 48 states.
Viewing Tips for the Best Experience
Experts emphasize that clear skies, minimal light pollution, and favorable weather conditions are essential for successful Northern Lights sightings. Skywatchers in the northern US and much of Canada should look toward the northern horizon during Tuesday and Wednesday nights for one of nature’s most spectacular light shows.
