The Northern Lights may be visible in the U.S. this Friday, Sept. 5, 2025, according to the latest forecast by the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.
Sky-watchers in 11 U.S. states may have a chance to see the aurora borealis on the northern horizon, though it arrives just before a full moon, seen as a total lunar eclipse or “blood moon” from some parts of the world.
The agency’s three-day forecast indicates a minor geomagnetic storm, measured at a value of up to G1 on a scale of G1 to G5. According to NOAA’s forecast, the Kp index — which provides a rough guide to the intensity of aurora displays — may reach 5.
Northern Lights: Latest Forecast
“G1 (Minor) geomagnetic storming is likely on 06 Sep due to recurrent, positive polarity coronal hole high speed stream influences,” reads an alert from NOAA, which refers to Universal Time. The storm is likely to begin late on Friday, Sept. 5 in North America. “Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.”
According to Spaceweather.com, the stream of turbulent solar wind expected to hit Earth is the result of a co-rotating interaction region expected to hit Earth on Sept. 5 — a transition zone between fast and slow streams of solar wind. “They’re a bit like mini-CMEs, containing shock waves and strong magnetic fields that can ignite high-latitude auroras,” says the website.
Aurora Alert: Where The Northern Lights May Be Visible
NOAA’s latest aurora viewlines indicate that aurora displays are a possibility in northern U.S. states and Canada, with 11 U.S. states having a chance after dark on Friday, Sept. 5.
U.S. states that may see aurora include Alaska and (northerly parts of) Washington, Montana, Idaho, Wyoming, North Dakota, South Dakota, Minnesota, Michigan, Wisconsin and Maine.

Northern Lights Friday: Effect Of The Full ‘Corn Moon’
Although it’s perfectly possible to watch strong auroras during a full moon, faint displays can suffer. That could be bad news this weekend, with the full “Corn Moon” rising on Sunday, Sept. 7, 2025.
Just a few hours prior, the full moon will have traveled through Earth’s shadow, causing a “blood moon” total lunar eclipse visible across Australia, Asia and Africa, with Europe glimpsing the event at moonset.
Wishing you clear skies and wide eyes.
