There's another supermoon on Sunday night—but this time it's a supermoon eclipse. As Time explains, the supermoon occurs when the moon is at its closest point to Earth, and Sunday's will be around 14% bigger than usual. And a lunar eclipse, of course, is when the Earth is between the moon and the sun, leaving the moon in Earth's shadow but still getting some sunlight. Oh, and it will also be a full moon. It's been 30 years since all three things (supermoon or "lunar perigee," full moon, and total lunar eclipse) have occurred at once, and it's not expected to happen again for 18 years. What can you expect? As the Christian Science Monitor puts it, "Earthly viewers will see a large 'blood moon' glowing burnt-red in the eastern sky."
And how can you see it? At least 2 billion people will be able to view it from North and South America, Europe, Africa, as well as parts of West Asia and the eastern Pacific. The moon will start moving into shadow at about 9:07pm Eastern time, and will be entirely in shadow and tinted red at 10:11pm for about 72 minutes.
