Head outside after the sun sets Thursday and you might catch a glimpse of a spectacular sight rising in the night sky.

Experts say July’s full moon could reduce sleep by up to 20 minutes on the evening of the 10th and as much as 90 minutes in the days leading up to and following it. Scientists in Switzerland previously found that, on the night of the full moon, people take on average five more minutes to fall asleep.

Skywatchers may have a harder time spotting July's full moon in Iowa. The evening of Wednesday, July 9, is expected to have 50-80% cloud cover across the state with some thunderstorms possible starting in western Iowa around 10 p.m. and moving across the state through the night, according to the National Weather Service.
