Beaver Blood Moon lunar eclipse on November 8th at moonrise
On November 8, 2022 full moon day, there will be a total lunar eclipse that will be visible in Asia, Australia, America and part of Europe. However, this eclipse is visible to Sri Lanka as a partial lunar eclipse at the moon’s rise.
The total eclipse begins at 1.32 p.m., the maximum occurs at 4.29 p.m. and the eclipse ends up at 7.26 p. m., Sri Lanka Standard time. Sri Lankans can view only the latter part of this safe naked-eye event as a partial eclipse with the moon rise at 5.48 p.m. from the eastern horizon. The partial phase of the eclipse ends up at 6.19 p.m. said Prof. Chandana Jayaratne, the Director of the Astronomy and Space Science Unit, Department of Physics, Colombo University.
This is the second and final total lunar eclipse of 2022 and is famously known as the Beaver Blood Moon lunar eclipse. The true maximum point of this eclipse cannot be seen in Sri Lanka because the Moon is below the horizon at that time. Since the Moon is near the horizon at this time, it is better to select a high point or find an unobstructed area with free sight to the east-northeast for the best view of the eclipse, said Prof. Chandana Jayaratne.
The next total lunar eclipse won’t take place until March 14, 2025.
Why do we call it a Beaver Blood Moon Eclipse?
All the full moons have popular nicknames. If the full moon in November falls before November 7, it is called the Hunter’s Moon. Otherwise, like this year, it is called the full Beaver Moon. The name Beaver is given due to the time of year when beavers available in many countries in the northern parts of the world prepare their dens for the coming cold months and stock up on food.
Despite its nickname “blood moon”, at the totally, eclipsed moon looks an orangey-copper reddish color and not a blood-red color.
During a total lunar eclipse, a full moon passes first into the penumbra or less dark outer shadow of the Earth and then enters into the Earth’s umbra or deep central shadow. At the totality, the only sunlight reaching the moon is light that passes through Earth’s atmosphere. Instead of expected black, it turns the lunar surface red because of Rayleigh scattering. The more the environmental pollution, dust or clouds in Earth’s atmosphere during the eclipse, the redder the Moon will appear.
