A Partial Lunar Eclipse is in store beginning Friday, November 19, 2021 at 12:02 a.m. The maximum or greatest lunar eclipse overnight will occur at about 3:03 a.m.

On November 18-19, 2021 there will be an “almost” total lunar eclipse for areas in the United States.




The Moon passes into the shadow of the Earth, creating a partial lunar eclipse so thoroughly that it can reasonably be called “almost total.” At the moment of greatest eclipse, at around 9:03 a.m. UT or Universal Time (3:03 a.m. CT), 99.1% of the Moon’s disk will be within the Earth’s umbra. This part of the eclipse is visible in all of North America, as well as large parts of South America, Polynesia, eastern Australia, and northeastern Asia.

In the Chicago area you will notice the partial lunar eclipse begin about 12:02 a.m. and reach “Greatest Eclipse at about 3:03 CST. Completion of the lunar eclipse will be about 6:00 a.m.

Clouds conditions are forecast to be at about 23% cloud cover at midnight, and about 4% cloud cover at 3:00 a.m. and for the rest of the night (early morning). Temperatures are forecast to be about 25-28°F after midnight.

This eclipse is part of an “almost tetrad”—a series of four big lunar eclipses in two years. Three of these eclipses are total, while the November 18-19, 2021, is a deep partial eclipse. So deep that it is almost a total eclipse.




The Moon is a Full Moon except during the eclipse. The Moon rises at 4:12 p.m. Thursday afternoon and sets 6:58 a.m. Friday — about one hour after the Partial Lunar Eclipse is completed.

Full Moon early Friday, November 19, 2021.
