The super moon phenomenon happens when the full moon coincides with the closest point of the moon's orbit to earth.
Full moons themselves are not rare, as they occur nearly every 29 days, but a blue moon is a rare event.
Sky watchers should not miss the chance the see the blue moon this Easter weekend. NASA says this particular event probably generated the phrase "Blue Moon," but volcanoes aren't the only reason a moon can look blue. The event can happen once in 2.66 years and whenever it takes place, the second full moon is called the "Blue Moon".

The term blue moon is a derivation from an Old English word for betrayer.
The exact time the moon will be full will be at 1.36pm BST, although obviously this won't be visible to us.
