On November 19, sky enthusiasts will enjoy the last partial lunar eclipse of 2021. The Moon will even redden a little.
A lunar eclipse occurs when the Moon enters the Earth’s shadow. This lunar eclipse will last 3 hours, 28 minutes and 24 seconds.
In Western countries, the November full moon is also known as the Beaver Moon, as it is the time when beavers prepare for winter.
Although partial lunar eclipses aren’t as spectacular as total eclipses, they occur more often, which means more viewing opportunities. This lunar eclipse will be visible from the Americas, Australia, and parts of Europe and Asia.
The lunar eclipse has 4 phases. As the Moon enters penumbra at 1:00 p.m., it is below the horizon. When the Moon enters complete darkness and reaches its maximum, in Hanoi it still cannot be observed. From the time the Moon begins to leave and return to the partial lunar eclipse at 5:47 p.m., you can observe until the eclipse ends at 7:00 p.m.
As the Moon approaches the darkest part of the eclipse, it will turn dark red or completely brown at its maximum.
Unlike a solar eclipse, a lunar eclipse can be observed with the naked eye. If you want to take a closer look at the moment when the Earth gradually “rips away” the Moon, you can use binoculars or a small telescope.
In November it is still cold, so dress warmly and bring the necessary tools about half an hour before use to be ready to observe.
