Northern lights spotted in Kentucky. See photos shared on Twitter

People in Kentucky and other states may have seen aurora borealis, or northern lights, Sunday night due to a geomagnetic storm.

The NOAA's Space Weather Prediction Center said severe geomagnetic storms had been expected to continue through Sunday night, causing the aurora to move toward states like Virginia, Arkansas and Northern California.

A geomagnetic storm is a severe disturbance in Earth's magnetic field and can cause widespread voltage problems, the service center said on Twitter.

According to Space Weather Watch, a Twitter account that tracks aurora forecasts and space weather, northern lights may have been visible in 30 states, weather permitting, including Indiana, Ohio and Kentucky. The best time to see northern lights is between 10 p.m. and 2 a.m., the NOAA website states.

Twitter users in Kentucky shared photos of the lights late Sunday night and early Monday.

"NORTHERN LIGHTS really popping through in Hatfield, Kentucky! I am in awe!!!" Jordan Smith, a meteorologist with ABC 36 News (WTVQ-TV) in Lexington, tweeted.

Other Twitter users said the lights were visible in Pikeville, Kentucky, which is near the border of West Virginia, and north of Lexington in Berry, Kentucky.

A solar storm caused northern lights to be visible in the U.S. last month, and sightings were reported in Washington, Montana, Wyoming, Minnesota, Wisconsin, South Dakota, North Dakota and New York.
