Tomorrow night, for the first time in 33 years, a total lunar eclipse will coincide with a “Supermoon.” University of Iowa physics and astronomy professor Robert Mutel told KCRG-TV it’ll be a “spectacular show.”
Beginning around 8 p.m. Sunday, the moon will enter the shadow of the Earth, transforming from a bright full moon to a copper-reddish color. “People like to call it blood red, but it’s really more coppery. It’s caused by the shadow of the earth, which is coppery colored itself because the sunlight is filtered through the shadow of the earth,” Mutel said.
The total eclipse will start at 9:11 p.m. and last for one hour and 12 minutes. There’s no need for special glasses or “filters” to watch the events unfold. “The naked eye is fine. If you have a pair of binoculars, that’s even better,” Mutel said. “If it’s clear on Sunday night, you can just sit down and enjoy the show.”
The next super lunar eclipse won’t happen again until 2033.
