Northern lights in Kentucky

Yes, but rarely: Kentucky needs a severe or extreme geomagnetic storm. In 2024 it got two, and during the May storm WEKU reported the aurora was visible throughout much of the state. Cameras show it far better than eyes at this latitude.

How strong a storm each city in Kentucky needs

The farther a place is from the magnetic pole, the stronger the geomagnetic storm needed to push the aurora into view. These levels come from each city's geomagnetic latitude and NOAA's storm scale, which says how far south aurora is usually seen at each level. They are for aurora low on the northern horizon from a dark spot; overhead displays need more. Across Kentucky the level ranges from Kp 7.5 (G4) in Ashland to Kp 7.8 (G4) in Paducah.

How often you can see the aurora in Kentucky

Kentucky lies between NOAA’s examples for strong storms (Illinois) and severe storms (Alabama). In practice the state needs a severe or extreme storm. Severe storms come on about 60 days per 11-year solar cycle, and extreme ones on only a handful. Even then the aurora usually sits low on the northern horizon. The table above shows each city’s level against tonight’s forecast.

Where to watch

  • Mammoth Cave National Park: a certified International Dark Sky Park in south-central Kentucky. Look for an open field with a view north.
  • Rural northern Kentucky farmland: open, rolling land along and south of the Ohio River, away from Louisville, Lexington and Cincinnati’s suburbs.
  • Lake shores: a big reservoir with open water to the north gives a view that hills don’t block.

Notable sightings

  • May 10–11, 2024: WEKU reported the aurora was visible throughout much of the commonwealth, with photos from places like Versailles. The National Weather Service in Paducah, whose forecast area includes western Kentucky, also listed it as a rare aurora sighting.
  • October 10, 2024: WKYT reported that many Kentuckians watched the northern lights from their backyards. The Paducah office listed it as its second rare aurora sighting of the year.

Tips for Kentucky

  • Use your phone. As an astronomy professor told WKYT, a phone camera pointed at the aurora for a few seconds picks up more light than the eye can.
  • Find an open northern horizon. Hills and woods block much of Kentucky’s low sky. Fields, lakeshores and overlooks work best.
  • Escape the city glow. Louisville, Lexington and the Cincinnati suburbs light up the sky for miles around. EKU astronomer Mark Pitts told WKYT the best thing to do is get north of any large city or town.

Dark-sky places near Louisville

Certified dark-sky places are among the best spots to watch for aurora: little light pollution and, often, open views to the north.

Questions and answers

Can you see the northern lights in Louisville or Lexington?

During the biggest storms, yes, mostly in photos. City lights hide faint displays, so drive into the countryside and face north.

Is Mammoth Cave National Park good for the aurora?

It is a certified International Dark Sky Park, so the sky is dark. Hills and forest block much of the low northern sky, so pick an open field or overlook.

Will Kentucky see the aurora again soon?

Only when a severe storm hits, and those cluster around the peak years of the 11-year solar cycle. Check the live forecast above when NOAA issues a storm watch.
