Supermoon lunar eclipse or “blood moon” to wow UK
Sunday, September 27, 2015, 09:40 GMT -
Only five total lunar eclipses have coincided with a supermoon since 1900. The last time it occurred was in 1982 and the next time it will happen is in 2033.
The moon will turn red as it passes through the shadow of the Earth – some sunlight still illuminates the moon hence the “blood moon” nickname – at 3.47am BST on September 28.

What is a Supermoon?
Some years ago, astrologer Richard Nolle coined the term 'supermoon' to denote when a full or new moon occurs when it is particularly close to Earth.
There are typically six supermoons every year. However, this particular full moon and total lunar eclipse are occurring at a slightly more special time of the year than a ‘normal’ supermoon. It is occurring during 2015's perigee full moon - the absolute closest full moon we'll see this year.
At this distance from us, the moon will appear around 14 per cent larger than usual.

Completing the Tetrad
The September 27 eclipse also marks the completion of a Lunar Tetrad - four consecutive total lunar eclipses occurring at approximately six month intervals.
Although some periods have gone by with no tetrads at all, when they do occur there can be up to eight in a century. The 20th century saw 5 tetrads, and the tetrad of 2014-2015 is the second of eight total between 2001 and 2100.
The first three eclipses of this tetrad took place on April 15 and October 8 of 2014, and April 4 of 2015.
