The northern lights are forecasted to reappear over Iowa Thursday evening, according to the Space Weather Prediction Center. The forecast suggests a strong chance of auroras across the northern United States.
Also called aurora borealis, these natural light displays occur in the northern hemisphere when charged solar particles enter the Earth's atmosphere.
NOAA explains auroras as “beautiful light curtains formed when energetic particles from the sun strike the atmosphere.”
A similar phenomenon in the southern hemisphere is known as aurora australis.
The predicted aurora visibility line crosses near Iowa’s southern border. Residents in northern Iowa are more likely to witness the lights.
However, cloud cover may obstruct the view in some areas:
The moon phase this night is a waning gibbous with 98% brightness, which may lessen visibility of the northern lights for observers in Iowa.
While the northern lights are likely visible in parts of Iowa Thursday night, weather conditions and the bright moon could limit how well they can be seen.
Author's summary: Northern lights may glow over Iowa Thursday night, but heavy clouds and a bright moon could dim the display for many residents.
