Eclipse 2018: Longest total lunar eclipse today – time, how to watch and more

TONIGHT a lunar phenomenon will grace the skies as the moon turns red during a total eclipse. Here is all you need to know about tonight’s Blood Moon.
A rare lunar event is taking place tonight, as the Moon undergoes a total eclipse, turning red in the process.
This will be the longest eclipse of the century and a real treat for stargazers and novices alike.

Why is the Moon turning red?
Tonight’s lunar eclipse will see the Moon turn eerily red/orange as it passes through the Earth’s shadow.
Known as a Blood Moon, this is a result of light refraction during the eclipse.

A lunar eclipse occurs when the Earth, Sun and Moon perfectly align creating a shadow.
Sunlight is refracted through the Earth’s atmosphere, removing all colours except those in the red colour spectrum.
These then bounce out of the Earth’s atmosphere and onto the Moon, causing the eerie red glow that we will see tonight.

Why is it the longest eclipse of the century?
The Earth is currently the furthest away possible on its rotation from the Sun, meaning the distance and angle of the shadow cast will take a long time to pass through.
The eclipse will last for one hour, 43 minutes and 35 seconds, and will be the 17th total lunar eclipse of the century.

The next will take place on January 21 2019.

What time will the eclipse begin?
The time that the eclipse will begin depends on where in the world you are.

In the UK, the beginning of the eclipse will not be visible as it will be below the horizon, but the maximum eclipse through to the end of the eclipse will be visible from 9.21pm BST.
Nigeria, Congo, Angola and Morocco will be able to see the Blood Moon from 8.30pm local time.

Germany, Spain, France, Italy, Egypt, South Africa and Austria will all be able to witness the whole of the Blood Moon from 9.30pm local time.

In Turkey and Kenya, the eclipse will be visible throughout all of its stages from the slightly later time of 10.30pm local time.
India will be able to witness the Blood Moon from 1.00am local time, whilst Bangladesh can see it from 1.30am local time.
From 3.30am local time, China and the Philippines will be able to see the eclipse and Japan can witness it at 4.30am local time.
Those wanting to watch the Blood Moon in Australia will have to get up early, as the beginning of the eclipse is visible from 5.30am.

How to watch the Blood Moon

Unlike a solar eclipse, a lunar eclipse is perfectly safe to look up at without eye protection.
To get the best view, being in a place with no light pollution such as the countryside or green open spaces will give an uninterrupted view.
