Did you see the “moon halo” Monday night?
Lisa Hudson of Knoxville did and used a fisheye lens attachment on her iPhone XS to capture it.
“This is the most amazing thing I’ve ever seen in the sky of Knoxville. My boys and I noticed it at around 11:30 p.m. Monday night,” she wrote in a message. “We watched it for over 30 minutes with no change.
“It’s called a moon ring halo. Rings around the moon are caused when moonlight passes through thin clouds of ice crystals high in the earth’s atmosphere! It helps to have a fisheye lens handy on your cell phone!”
Scientists call this phenomenon “22-degree halos” because the ring has a radius of approximately 22 degrees around the moon, according to the website EarthSky. They are also called lunar halos and winter halos.
The website also noted there’s an old weather saying that a ring around the moon means rain soon and there’s plenty of rain coming in our forecast.
