A Full Round moon
Depending on your location, December 20 or early morning December 21, the full moon will be darkened by Earth’s shadow as the our planet passes between it and the sun.
This spectacle will be visible across North and South America, northern and western Europe, and a small part of northeast Asia, including Korea and most of Japan. Up to a 1.5 billion people will watching this extravaganza in the sky!
NASA reports that this is the first time an eclipse has coincided with a solstice since December 21, 1638, with the next one visiting us again around 2094. So set your clocks for this once in a lifetime show as the moon enters Earth’s dark inner shadow, around 1:33 AM EST.
For a clear view of tonight’s lunar eclipse or any lunar weclips, look though binoculars or a telescope. A moon eclipse is safe to watch, unlike a solar eclipse, which can cause eye damage when not protected.
