Get ready, aurora chasers: The northern lights may put on a good show across parts of the U.S. tonight as a high-speed solar wind stream is forecast to slam into Earth’s magnetic field.
Forecasters at NOAA’s Space Weather Prediction Center (SWPC) predict possible minor (G1) geomagnetic storm conditions for Oct. 28 and Oct. 29 (starting in the early hours of Oct. 28), with a chance of stronger moderate (G2) storming if conditions intensify. The U.K. Met Office echoes this forecast, predicting that auroras could dip into latitudes around Scotland or the northern U.S., depending on the timing and strength of the incoming solar wind.
A combination of fast solar wind from a large Earth-facing coronal hole and possible influence from a weak coronal mass ejection (CME) that left the sun on Oct. 23 could cause solar wind speeds to climb significantly from Oct. 28 through Oct. 29 — great news for aurora chasers.
According to NOAA’s Kp index forecast, geomagnetic storming is expected to occur intermittently between 11 p.m. EDT tonight (0300 GMT on Oct. 28) and 5 p.m. EDT Oct. 29 (2100 EDT). This makes the next couple of nights the ideal time to watch for dazzling aurora displays.
Based on the latest NOAA aurora forecast map, the following 14 U.S. States appear fully or partially above the aurora view line:
However, auroras are highly unpredictable. Even if you’re within the view line, you’ll still need cloud-free skies, minimal light pollution, a clear view northward and a little bit of luck to catch the show.
If you’re in one of the 14 U.S. states listed above, here are some tips for catching a glimpse of the display.
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.
