The northern lights could put on a show tonight and through the weekend as ongoing geomagnetic storm conditions driven by turbulent space weather may push aurora farther south than usual.
Earth is currently reverberating from a solar storm impact that occurred overnight on June 12-13, during which moderate G2 geomagnetic storm levels were reached. A co-rotating interaction region (CIR) — a turbulent region in the solar wind in which fast-moving streams collide with slower wind ahead of them — is also on the way, with the effects expected around June 14.
NOAA's Space Weather Prediction Center (SWPC) has issued a moderate (G2) geomagnetic storm watch for June 14 due to the incoming solar wind from a large Earth-facing coronal hole. The U.K. Met Office echoes this forecast, predicting moderate (G2) geomagnetic storms on June 13-14, with activity expected to decline to unsettled levels by June 15-16.
What does this mean?
A G2 storm can shift the aurora oval — the ring-shaped zone where auroras typically form — farther south, allowing skywatchers across parts of the northern U.S. a chance to catch a glimpse of the elusive lights, weather and dark skies permitting. Geomagnetic storms are ranked using a G-scale, which ranges from G1 (minor) to G5 (extreme).
States that could see auroras tonight
Below, we have listed 18 states that appear either fully or in part above the possible view line for auroras tonight, according to NOAA's Space Weather Prediction Center. They're ordered from most likely to least likely based on their proximity to the center of the auroral oval and how much of each state is within or near the view line.
Keep in mind, auroras are fickle. Sometimes they show up much farther south than expected and other times they don't appear at all. Many conditions have to align for the perfect display.
- Alaska
- Montana
- North Dakota
- Minnesota
- Wisconsin
- Michigan
- South Dakota
- Maine
- Vermont
- New Hampshire
- Idaho
- Washington
- Oregon
- New York
- Massachusetts
- Connecticut
- Rhode Island
- Wyoming
Viewing conditions also depend on more than just geomagnetic activity. Cloud cover, light pollution, and the brief summer night can all affect visibility.

How can I see the northern lights from where I live?
If you find yourself in one of the 18 states listed above (or simply want to try your luck) head to a dark, north-facing spot away from city lights. As we approach the summer solstice on June 20/21, nights are growing shorter, so your best window for viewing may be in the early morning hours, around 1 to 2 a.m.
Interested in tracking space weather and knowing when and where to spot auroras? Download a space weather app that provides forecasts based on your location. One option I use is "My Aurora Forecast & Alerts," available for both iOS and Android. However, any similar app should work well. I also use the "Space Weather Live" app, which is available on iOS and Android, to get a deeper understanding of whether the current space weather conditions are favorable for aurora sightings.
