The coappearance of a total lunar eclipse and a supermoon is a result of sun, moon and earth getting line up together.
This ( Sunday:January 20, 2019) will be the only total lunar eclipse this year and next. At the same time, the moon will be ever so closer to Earth and appear slightly bigger and brighter than usual i.e a supermoon.
Statement issued by Patrick Hartigan (astrophysicist, Rice University) states,“It not only is a supermoon and it’s a total eclipse, but the total eclipse also lasts pretty long. It’s about an hour.”
The whole eclipse starts Sunday night or early Monday, depending on location , and will take about three hours.
If the skies are clear, the entire eclipse will be visible in North and South America, as well as Greenland, Iceland, Ireland, Great Britain, Norway, Sweden, Portugal and the French and Spanish coasts. The rest of Europe, as well as Africa, will have partial viewing before the moon sets.
During the whole show, the moon will look red because of sunlight scattering off Earth’s atmosphere. That is the reason why an eclipsed moon is also termed as a blood moon. The full moon of January is also known as the wolf moon.
So informally speaking, the upcoming lunar eclipse will be a super blood wolf moon.
