Space weather experts report that solar storms may create bright auroras visible across several northern U.S. states this week. The phenomenon results from a large coronal mass ejection that the sun released and is now heading toward Earth.
The coronal mass ejection, described as a powerful burst of solar energy, is expected to reach Earth between Thursday evening and Friday morning. This solar activity prompted a strong geomagnetic storm watch from forecasters at the National Oceanic and Atmospheric Administration (NOAA).
How vivid and widespread the auroras become depends on the exact timing of the solar burst and its interaction with Earth’s magnetic field. Locations across the northern United States could have the best chance to spot the northern lights if the conditions align.
“If the timing is right, it’s possible auroras will quite likely spin up overnight,” said Shawn Dahl, space weather forecaster with NOAA.
Authorities continue to track the storm closely. According to Dahl, significant disruptions to radio or communications systems are not expected at this time.
NOAA offers an aurora tracking tool to help users find where and when viewing chances are highest. Those in northern regions should monitor local forecasts for updates.
