The northern lights could light up skies across the U.S. tonight, as a high-speed solar wind stream from a coronal hole and an incoming coronal mass ejection (CME) are forecast to hit Earth, according to the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center.
The combination of the incoming solar wind and the CME released during Monday’s X-class solar flare could push geomagnetic conditions to moderate (G2) levels with a brief chance of strong (G3) if both the fast solar wind and CME arrive close together.
Based on the latest NOAA aurora forecast map, the following 15 U.S. states appear fully or partially above the aurora view line:
Remember, auroras can be fickle creatures. The list is based on current forecast data, but if conditions strengthen and skies are clear, auroras could reach much farther south than expected.
Then again, if conditions don’t align, we might end up with a “nothing burger” and no auroras at all.
The northern lights could be visible across 15 U.S. states tonight (Dec. 3-4) as soon as it gets dark, so it’s worth keeping an eye on the sky throughout the evening, especially in areas with clear, dark skies.
According to NOAA’s 3-day forecast, geomagnetic storm activity is expected to be best at the following times:
If you live in one of the 15 U.S. states forecasted to catch a glimpse of the northern lights tonight, there are a few things you can do to give yourself the best chance of seeing them.
We recommend downloading a space weather app that provides aurora 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.
