What Is a Blood Moon
A blood moon is the reddish color the Moon takes on during a total lunar eclipse. Sunlight passes through Earth’s atmosphere, which scatters blue light and bends red light onto the Moon. The 2019 event was called a super blood wolf moon because it coincided with the Moon being near perigee, its closest point to Earth.
When and Where the 2019 Blood Moon Was Visible
The total lunar eclipse occurred on January 20–21, 2019. It was visible from North and South America, Europe, and western Africa. The entire eclipse, including partial and total phases, was widely observed from these regions under clear skies.
Why People Track Blood Moon Events
People track blood moons because they are predictable celestial events that combine astronomy with cultural and historical interest. NASA and other scientific sources provide precise timing and visibility maps. For more details, see NASA’s lunar eclipse page at https://science.nasa.gov/lunar-eclipses/.
