Longest Partial Lunar Eclipse in Almost 600 Years is Happening This Week
Nasa says the eclipse will be three hours and 28 minutes long, which is the longest partial eclipse of this century and the longest in 580 years.
For U.S. East Coast observers, the partial eclipse begins a little after 2 a.m. Friday, November 19th, 2021 reaching its maximum at 4 in the morning. For observers on the West Coast, that translates to beginning just after 11 p.m. Thursday, November 18th, 2021 with a maximum at 1 a.m. Friday, November 19th, 2021.
And you don't need any special glasses to see it, unlike during a solar eclipse. All you need is to be able to wake up and get out there, along with a coat to keep warm during the chilly November night.
A lunar eclipse happens when the sun, Earth, and a full moon form a near-perfect lineup in space. The moon gradually glides into Earth's shadow, until most of the lunar disk turns from silvery gray to an eerie dim orange or red. Then events unfold in reverse order, until the moon returns to full brilliance.
November's full moon is known as the Beaver Moon, named for the time in days past when beavers are preparing for winter
Technically this full moon is due to occur early on Friday morning, November 19, at 3:58 a.m.ET, according to NASA, but it will still appear full for about three days around this time from Wednesday to Saturday.
This will be the last lunar eclipse of the year. There will be two total lunar eclipses visible in most of the U.S. in 2022, one in May and the other in November according to NASA.
