A blood-red "supermoon" lunar eclipse will inspire awe, and perhaps dread, across the world in an event that has not occurred for 30 years.

The eclipse, with the moon near to its closest point to the Earth, marks the completion of an unusual string of four total eclipses at six monthly intervals known as a "tetrad". The previous three occurred on April 15 2014, October 8 2014, and April 4 2015, but were not visible from the UK. A cycle like this hasn't been seen since 1982 and won't begin again until 2032.
Observers on Earth will see the large moon turn red, due to sunlight being scattered by the Earth's atmosphere. Some onlookers may feel a sense of foreboding, as so-called "blood moons" have been seen as ill-omens by superstitious people, religious groups and astrologers throughout the ages.
From the UK, the moon starts to enter the Earth's shadow at 01:10 on Monday morning, and will completely within the shadow from 03:11 to 04:24. The eclipse will end at 06:24, when the moon leaves the Earth's shadow.
Leading amateur astronomer Robin Scagell told the Telegraph that the phenomenon is well worth staying up for: "From a UK point of view, it's happening at a most unsuitable time, but I would say it's definitely worth setting the alarm for to look out and see this red moon hanging over the tree tops."
