You will have to be very determined to catch it, but anyone who wakes up extra early on Monday morning will be in for a treat.
A very lean eclipse is quite rare in our skis, but is a spectacular event so you might want to put your alarm now.
Known as a blood moon because the moon changes temporarily to a reddish color in front of your eyes, it should be evident to many people in the UK – providing them get out of bed, that is.
What is a Blood Moon?
A blood moon is the eponymous name for a complete lunar eclipse, which passes the sun and moon when it shines, and casts a shadow over the moon as the sun sets.
During the process, some sunlight filtered by the Earth's atmosphere, reflecting on the moon giving a red appearance.
Why is it called a blood moon?
The term blood lance harkens back to a time when people were superstitious about the influence of a lunar eclipse, but also when people didn't know what's going on.
"The true reason that the term blood moon is enough for people to be terrified of the oblique skulls – thousands of years ago, if the moon suddenly turned red without warning in the sky, people would look up and be terrified," Tom Kers explained. An astronomer from the Royal Observatory Greenwich.
"That would have seen a sign or ohm of something terrible happening, as the moon looks like it's stained with blood at that point.
"It may evoke something I believe in the moon's way out, but the real technical deadline would be a mere lunar eclipse."
What is significant about the blood moon?
The most significant thing about this year's blood moon is that it will be the last of its kind to fall for a couple of years.
"This is actually the last complete lunar eclipse counts somewhere on earth until May 2021, so we go into this unusual lull in whole lunar oblcps over the next couple of years," Mr Kerss continued.
"So this is a really good one to catch up with as it is going to be a long time before you get another one like this – we will have other lunar obliques, we just won't have anything quite as spectacular until May 2021."
Will the blood be visible from the UK?
Yes, the monkey's blood will be visible from the UK, weather permitting.
This is a setting for lunar eclipse, which means that the moon is lower under the lip, so it will start in the south-west at a reasonably high angle, but will end up low in the west by the time the moon really is. Getting the deepest part of the eclipse.
"We are talking about 20 degrees above the horizon," Mr Kerss said.
"If you live in an urban or suburban area, usually 20 degrees from your local horizon, it is obscured by buildings or trees, so it's nice to have a good, clear, western view if you want to go out and place it. Or get a good high window that faces west and maybe looks from there.
What time will the blood moon take place?
The eclipse begins at 2.36 am on Monday, January 21, though observers are unlikely to see anything until much later in the morning.
The best time is around 5.12m to capture the maximum eclipse, when the moon is completely submerged within the Earth's shadow.
"The moon will be red between 4:40 and about 6:45, so it's actually more than an hour to observe the blood moon phenomenon where the moon is totally obliterated," Mr.
The Royal Museums Greenwich will also host a Facebook live event from 4:00 am, where viewers can watch events unfold.
Do I need a telescope to photograph the eclipse?
Observers do not need a telescope to see or photograph the eclipse – Mr Crisis says a standard DSLR camera should be able to capture the images.
For the sharpest photos, use a tripod or shutter far, so camera usage won't shake the picture as it is captured.
Using the longest lens to capture more detail of the moon and color gradient. If you do not have access to a long lens, wait for the moon to get lower and closer to the horizon, and frame the eclipse with buildings or scenery instead.
When was the Last Blood Moon?
The recent blood was in July 2018, although clouds largely obscured the celestial phenomenon in the UK.
