A penumbral lunar eclipse can be a bit hard to see as the shadowed part is only a little bit fainter than the rest of the Moon As the Moon passes through the shadow of Earth it appears in orange and red hues. A total lunar eclipse occurs when the earth passes exactly between the sun and the moon. The term "super" is in reference to the fact that the moon will be near its closest distance to Earth during the eclipse, while the "blood" part is due the reddish color the moon will experience during totality - the moon won't disappear entirely.
As a bonus, Sunday's eclipse will occur during a "supermoon" when it is closest to Earth in its orbit and therefore appears bigger and brighter.
He said around the globe, the eclipse is expected to take place across North and South America, Western Europe, North and West Africa and Asia.
In January, the full moon is also sometimes known as the wolf moon or great spirit moon - hence the super blood wolf moon. It is a rare event and we're told it will be quite the sight to see. The super moon is the first of three this year. The total eclipse, lasting 62 minutes, will start at 11:41 pm EST Sunday (09:41 am PST Monday).
It's the only total lunar eclipse of 2019.
"The Sun's red light is scattered much less by air, and is bent by Earth's atmosphere in a process called refraction, traveling all the way through it to light up the Moon's surface".
About 6:30 p.m., the penumbra or lighter outer shadow of Earth will begin falling on the moon. Sunlight passing through Earth's atmosphere will light the moon in a dramatic fashion, turning it red.
Next chance for Americans to see a total lunar eclipse is 2022.
"Viewers will see a normal full moon at first starting at around 10:35 p.m".
The penumbral eclipse starts at 9:36 p.m. E.T. on January 20, according to the site.
Europeans last saw a total lunar eclipse in July 2018. Unlike solar eclipses, you don't need eye protection to witness this one, and if the sky above is clear, stargazers should be able to look on from cities and villages alike.
