Ok, the actual words are 'Blue Moon, I saw you standing along', I just thought I'd do a play on the song. Not only do we have an eclipse this Friday for those in Europe but we also have a Supermoon. A Supermoon is when the moon comes closest to the Earth and therefore appearing much bigger and brighter than it would otherwise do. So after the event, in the evening, look at the moon, it should be bigger and brighter, that is if its not cloudy. As for what a Blue Moon is, it refers to a second full moon in a Gregorian Calendar Month.
