Next Week’s Partial Lunar Eclipse Will Be Longest for Next 648 Years

Another cool thing about this partial lunar eclipse is its duration. The penumbral eclipse, in which the Moon passes through both the inner and outer portions of the Earth’s shadow, will last for 6 hours and 1 minute, while the umbral eclipse, or the casting of the inner shadow, will last for 3 hours and 28 minutes, according to NASA. The Moon will be near apogee (i.e. the Moon’s furthest distance from Earth along its orbit) during the partial lunar eclipse, hence the extended astronomical show.

EarthSky says the upcoming lunar eclipse will be the longest since February 18, 1440 (seems like just yesterday) and that another of this extreme duration won’t happen again until February 8, 2669 (mark your calendars). That’s a stretch of 1,229 years, so keep that in mind if you’re on the fence about waking up early.

On that topic, the partial lunar eclipse of November 19 will be visible across much of the globe, including the Americas, eastern Asia, Australia, and the Pacific Region. For observers in North America, the show will start shortly after 2:00 a.m. ET (for observers on the U.S. West Coast, that means 11:00 a.m. PT on November 18), with the peak happening just after 4:00 a.m. ET, NASA says.

The lunar eclipse won’t be visible to observers in Africa, the Middle East, or western Asia, but not to worry—lunar eclipses tend to happen about twice a year. What’s more, a total lunar eclipse is expected the evening of May 15, 2022.
