A partial lunar eclipse occurred on 19 November 2021. The eclipse occurred towards a micromoon.[2] This was the longest partial lunar eclipse since 18 February 1440, and the longest until 8 February, 2669; however, many eclipses, including the November 2022 lunar eclipse, have a longer period of umbral contact at next to 3 hours 40 minutes.[3] It was often referred to as a "Beaver Blood Moon" although not technically fulfilling the criteria for a true blood moon (totality).
This lunar eclipse was the second of an almost tetrad, the others being 26 May 2021 (T), 16 May 2022 (T) and 08 Nov 2022 (T).
