Is Seattle getting a glimpse of the near-total lunar eclipse this week, the longest of the century? Here’s what we know

An almost total lunar eclipse is expected to be visible to large parts of the United States later this week, but the weather could potentially hinder Seattle’s view of the celestial event.

The partial eclipse will be the longest of the century, lasting a total of 3 hours, 28 minutes and 23 seconds starting around noon. 23:18 PST on Thursday, according to NASA’s full moon guide. During the event, the Earth, the sun, and the moon are close in line with the Earth in the center, casting the earth’s shadow on the moon.

The maximum eclipse when the moon is closest to the center of the shadow is expected to occur around noon. 01:02 PST on Friday. Over 97% of the moon’s surface will appear covered, leaving only a small tile on the left side to look bright, while the rest of the face will have a deep red or ocher color.

But the display of the eclipse is largely dependent on whether the weather remains clear. After Monday’s wet and windy stormfront, the forecast from the National Weather Service (NWS) in Seattle currently predicts that the next active weather system will move across the region on Thursday, potentially blocking any view of the eclipse that evening.

“A weather system will pass mainly south of the area later in the week – but the southern half of western Washington may see some rain on Thursday,” the NWS wrote in their Tuesday forecast.

If the conditions for seeing the sky are not favorable on Thursday, the eclipse can also be viewed online via Virtual Telescope Project 2.0 and Time and Date’s livestream video.

The moon will remain full – in what is called a “Beaver Moon” for the month of November – until Saturday morning.
