A dazzling northern lights show lit the skies above Northwestern states and Canadian provinces, according to social media accounts.
Social media reports verified by NBC News showed the lights visible in Minnesota, Alaska, Washington, Alberta, Manitoba and British Columbia.

The aurora borealis show was caused by what the Space Weather Prediction Center, which is part of the National Oceanic and Atmospheric Administration, said was a G2, or moderate, geomagnetic storm.
A G2 storm caused by a solar flare, or coronal mass ejection, can cause problems on Earth: Power systems at high latitudes can experience fluctuations, voltage alarms and transformer damage, and spacecraft may need to correct their orbits.

G2 storms cause aurora borealis shows as far south as New York and Washington state, according to NOAA.
Recent research into the aurora borealis suggests that the solar-charged light show may even produce faint clapping sounds, NBC News reported.
