Eyewitness News viewers asked plenty of questions about a halo around the moon Monday night. Derek explains the science behind the event in this video.
Here's Carl Arredondo's text explanation:
"We've been getting lots of cool photos of the halo around the moon. This is pretty common and it happens around the sun and the moon. When we have cirrus clouds pass in front of the moon or sun, this can happen. The cirrus clouds are made up of ice crystals and act like a prism and bend the moon or sunlight to form a halo."
