What is a partial lunar eclipse?

Several times a year, the Earth comes between the Sun and the Moon, blocking the sunlight that illuminates our natural satellite. Thus the Earth’s shadow covers the Moon, and the sunlight doesn’t reach the lunar surface. This is called the lunar eclipse; it occurs only during the Full Moon and is visible at nighttime. A partial lunar eclipse, in its turn, means that the Earth’s shadow doesn’t fully cover the lunar disk and a part of it remains illuminated.

Lunar eclipses are pretty spectacular as the Moon appears blood-red during these events. It happens because light from the Sun has to pass through the Earth’s atmosphere that filters out most blue light but lets in the red light.

Unlike solar eclipses, lunar ones are safe for your eyes and can be seen without special eye protection. To learn more about this phenomenon, watch our video about lunar eclipses.

Partial lunar eclipse in 2021

The partial lunar eclipse will occur on November 19, 2021. It will be the longest partial lunar eclipse between 2001 and 2100 with a duration of 3 hours, 28 minutes, and 23 seconds. It also will look almost as spectacular as the total eclipse — up to 97% of the lunar disk will slip into the Earth’s shadow!

The area where this lunar eclipse, or at least its part, will be visible is huge! It includes North America (the best location for observation), parts of Europe, Alaska, Australia, New Zealand, Japan, and the Pacific Ocean. From western Asia, Australia, and New Zealand the early stages won’t be visible as they occur before moonrise. Also, Western Europe and South America will miss the end of the eclipse because of the moonset. Observers from Africa, the Middle East, and western Asia won’t see the event at all.

To check if the eclipse is visible from your exact location, use Eclipse Guide. The app will show the Moon’s path during the eclipse, the precise map of the eclipse, and other handy information.

What is a Beaver Moon?

The Full Moon of each month has a unique name that dates back to Native American, Colonial American, and European folklore. The Beaver Moon is called so because around this time, hunters would trap beavers for their thick fur ahead of the chilly season. This is also a time of the year when beavers begin to hide in their lodges, having saved enough food stores for the winter.
