Wikipedia page for this celestial event
On November 8th, 2022, many people in China were able to witness the stunning sight of a total lunar eclipse. The moon appeared red, earning it the nickname "beaver blood moon" in some media coverage. This celestial event was the fourth and final eclipse in an almost tetrad, and was also part of the Saros cycle 136.
It was visible on the rising moon in China and the far northeast of Europe, and on the setting moon in South America and eastern North America. Many people in China took the opportunity to observe and photograph this rare occurrence, and some even held viewing parties to share the experience with friends and family.
This total lunar eclipse was the third of five Metonic cycle lunar eclipses on the same date, 8–9 November. The Metonic cycle repeats almost exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.
The next total lunar eclipse in this series will take place on November 8th, 2041, and is sure to be another highly anticipated event for Chinese skywatchers. It will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). This lunar eclipse will also be related to two hybrid solar eclipses of Solar Saros 143.
