A partial lunar eclipse will take place on Friday, November 19, 2021. The eclipse will occur towards a micromoon. This will be the longest partial lunar eclipse since 1440, and the longest until 2669; however, many eclipses, including the upcoming November 2022 lunar eclipse will have a longer period of umbral contact at next to 3 hours 40 minutes. This eclipse has a long partial phase primarily because it is entirely partial. Any total eclipse includes a period of more than 97% partiality like the maximum eclipse point of this one. Unlike a total solar eclipse, extended duration is not sought after by observers.
