The partial lunar eclipse will take place this evening, August 7, and will be visible from Europe, Africa, South and East Asia and Australia.
In London the penumbral eclipse will be visible at 9:50 pm, the partial eclipse will not be visible as it will happen below the horizon.
A partial lunar eclipse is when the earth moves between the Sun and Moon but they do not make a perfectly straight line.
A small part of the moon’s surface is covered by the central darkest part of the earth’s shadow called the umbra, the rest of the moon is covered by the earths outer shadow called the penumbra.
For a partial lunar eclipse to occur there must be a full moon, and the sun, earth and the moon must be aligned almost in a straight line.
The penumbral eclipse means that it is only the outer shadow of the earth that is covering the moon, so in the UK we will miss the main event of the central shadow of the earth covering the moon as it will be under the horizon.
However, we will see some eclipsing.
Eclipses come in pairs
A lunar eclipse, such as tonight’s, always occurs about two weeks before or after a solar eclipse, as will happen on August 21 this month.
An eclipse of the sun is a solar eclipse, this is when the moon’s shadow falls on the earth, a lunar eclipse is when the earth’s shadow falls on the moon.
This will be the last lunar eclipse of the year.
The phase that will be visible in the UK will be hard to distinguish as the Earth’s outer shadow will only make some of the moon slightly dimmer.
You won’t need any special equipment to see the partial lunar eclipse, you just need to be aware of the exact time and date of the eclipse, the weather forecast and you might need some warm clothes if you go outside.
If you don’t want any of that bother you can always watch the livestream of the astrological event.
