The northern lights are forecasted to return to Iowa skies on Thursday evening, November 7, according to the Space Weather Prediction Center. This natural light display is expected to be visible across the northern United States.
The northern lights, or aurora borealis, appear as glowing light curtains caused by energetic particles from the sun striking Earth's atmosphere. These displays occur in the northern hemisphere, while a similar phenomenon called aurora australis happens in the southern hemisphere.
NOAA describes auroras as “beautiful light curtains formed when energetic particles from the sun strike the atmosphere.”
The forecast indicates the northern lights’ visible zone will cross near Iowa’s southern border, though residents in northern Iowa will likely have better chances to see the display. However, cloud cover may affect visibility for many.
The moon phase will be a waning gibbous with 98% illumination, which might reduce the visibility of the northern lights for some viewers.
Author’s summary: Northern Iowans may glimpse the northern lights Thursday night, but cloud cover and bright moonlight could limit visibility across much of the state.
