The total lunar eclipse — when the moon is fully shaded by the Earth — is expected a little before 8 p.m. Sunday, with the whole show to last until 9:27 p.m.
Nighttime sky watchers are expected to be double-wowed Sunday evening with a supermoon and a total lunar eclipse.
NASA says this is the first time in more than 30 years the combination has happened, and with Seattle’s cloud cover expected to clear out, those in the Seattle area should be able to see it.
The eclipse begins at 5:11 p.m. Sunday, so it will already be in progress when the moon rises at 6:55 p.m., according to the Pacific Science Center. The total eclipse — when the entire moon is shaded by the Earth — is expected at 7:47 p.m., and the whole show is expected to be over by 9:27 p.m.
A supermoon occurs when a full or new moon makes its closest approach to Earth. It appears 14 percent larger and 30 percent brighter in the sky, according to NASA.

A total lunar eclipse happens when the moon passes completely into the shadow of the Earth, taking on a reddish color, which has come to be called a “blood moon.” The red color occurs because filtered sunlight shines through Earth’s atmosphere, making the moon appear red.
There won’t be another total lunar eclipse until 2018.
The next supermoon eclipse will occur in 2033.
The Pacific Science Center said for the best view of the eclipse, find an area with an unobstructed view to the east. And while a dark sky location is ideal, it is not a necessity to enjoy the event.
