The full moon will begin Election Day on Tuesday, November 8, with a coppery shade of red in the sky.

The eclipse, the second of the year, will begin at 3:02 a.m. ET, with the moon initially dimming for the first hour, and will end at 8:50 a.m. ET.

The moon will take on a dark reddish hue, giving rise to the term "blood moon."

According to NASA, the stunning effect will be visible beginning at 5:17 a.m. ET.

“They aren’t that common, so it’s always nice to get a hold of them when you can,” said Dr. Alphonse Sterling

On average, a total lunar eclipse occurs once every 1 ½ years, with the next total lunar eclipse not occurring until March 14, 2025.

A penumbral lunar eclipse occurs when the moon passes through the Earth's outer shadow, or penumbra, creating a more subtle visual effect.

Those watching the total lunar eclipse will be able to see the curvature of Earth's shadow as it slowly swallows up the moon.
