Blue Moon

A Blue Moon is the second of two full Moons in a single calendar month. A full Moon occurs roughly every 29½ days and on the rare occasions when the full Moon falls at the very beginning of a month there is a good chance a Blue Moon will occur at the end of the month.

A 'Blue Moon' curse is powerful curse in Italian witchcraft. To say someone is born under a bad (astrological) sign with a blue moon in their eyes means that they were cursed at birth, and will never lead a good life:

"Woke up this morning, got yourself a gun;
Mama always said you'd be The Chosen One
She said: "You're one in a million and you've got to burn to shine,
but you were born under a bad sign, with a blue moon in your eyes."

"Woke up this morning", The Sopranos soundtrack (1999), Alabama 3

Black Moon

A black Moon is the name given to the second new Moon in a calendar month. A new Moon is the first phase of the 29.53-day lunar cycle as the Moon orbits Earth. At this phase of the cycle, the Moon is invisible to the naked eye as its illuminated side faces away from Earth and towards the Sun, meaning it is shrouded in darkness and thus hard to see.

Supermoon

A Supermoon ('Perigee Full Moon') is a new or full Moon which occurs with the Moon at or near (within 90 per cent of) its closest approach to Earth in a given orbit. This results in what's known as a perigee-syzygy full Moon, referred to in the popular press as a 'Supermoon'. Syzygy is a term describing when three celestial bodies are in a line. At perigee the apparent size of the Moon is maximised and this particular full Moon will have the largest apparent diameter since 26th January 1948. Although this sounds dramatic, the difference between November's full Moon and those of October and December is actually quite small. The Moon's full phase is unfortunately timed for the annual Leonid meteor shower which peaks on 17th November, moonlight drowning out all but the brightest meteor trails.

Each full Moon of the year is given a name:

Blood Moon

Also known as a Supermoon lunar eclipse occurs when the shadow of Earth casts a reddish glow on the Moon, the result of a rare combination of an eclipse with the closest full Moon of the year. There was one in September 2015, and before that in 1982 but the next one will not occur until 2018.

Longest lunar eclipse of the century

Spectacular blood moon will be visible from dusk on Friday, 27th July, until Saturday morning.

Britain will witness a spectacular and rare celestial spectacle this week. At dusk on Friday, the full moon will rise and reveal itself coloured a deep red. The nation will then experience a blood moon or, as astronomers term it, a total lunar eclipse. And this week promises to be a special one, for it will be the longest-lasting total lunar eclipse of the 21st century. After it rises in the south-east - at around 8.50pm in London - the moon's eclipse will continue until early on Saturday. "Weather permitting, it should give Friday evening a special, exciting edge," said Sheila Kanani of the Royal Astronomical Society.

Blood moons have only recently been welcomed on Earth. Their deep red colour has usually been seen as an omen of terrible events. The Book of Joel in the Hebrew Bible warns that "the sun will turn into darkness, and the moon into blood, before the great and terrible day of the Lord comes."

Today scientists have a more prosaic explanation for the moon's crimson transformation. It is caused when the moon passes through the shadow of the Earth. However, its disc does not go completely dark because some sunlight - mainly the longer-wavelength, redder end of the spectrum - passes through our atmosphere and is bent around the edge of our planet so that it falls on to the moon's surface. In effect, it is the light of sunrise and sunset on the Earth that will give the moon its red glow on Friday.

Unlike total solar eclipses, which occur when the moon's disc passes in front of the sun and completely blots out sunlight for only a few minutes, a blood moon is a fairly leisurely affair. "It will last several hours - when you get a real feeling of the Earth and moon shifting in space," said astronomer Tom Kerss, of the Royal Observatory Greenwich, which plans to stream live pictures of the event on Friday. "You get a true sense of the solar system moving - and that in itself is a really dramatic experience."

For good measure, there is no need to wear goggles or filters to watch a blood moon as is necessary with solar eclipses. "It is safe to watch with the naked eye," said Kerss. "You could use a telescope but, to be frank, it will be just as dramatic to watch it without aids as the red moon slowly rises in the sky over Britain and the shadow of the Earth passes from its surface."

Strawberry Moon

A rare event when there's a full Moon on the same day as the summer solstice. It happened in June 2016 for the first time since 1967 when 17 hours of sunlight gave way to a bright moonlit sky. The Moon appears pink or red and its romantic label was coined by the Algonquin tribes of North America who believed June's full Moon signalled the beginning of the strawberry picking season.
