Skiers on New Year's Eve will get best view of the blue moon

It may become known as the great blue moon boo boo.

Reports of Australians celebrating New Year's Eve under a rare blue moon have been shot down by astronomers.News websites, including this one, were quick to follow up on a report in yesterday's The Age newspaper, which referred to a blue moon occuring on New Year's Eve.

The only problem is, that report was incorrect.In Australia, at least.The phrase blue moon refers to when a second full moon occurs within a calendar month. With the lunar cycle taking roughly 29.5 days, it generally happens every two to three years. The moon itself does not change colour.

A blue moon is scheduled for 7.13pm New Year's Eve, but astronomers work in Greenwich Mean Time.

Because Australia's time zone is ahead of England, the full moon will actually occur at 5.13am January 1, Brisbane time.The fact that it doesn't fall in the same month means it can no longer be considered a blue moon.

Mark Rigby, curator of the Brisbane Planetarium, said the term full moon referred to the specific point when the moon was on the opposite side of the Earth to the sun."If you were in London you could celebrate on New Year's Eve under a blue moon, but not at our latitude," Mr Rigby said.

"It is a specific moment in time when you have the sun, Earth and moon all in a straight line."

Australians devastated at losing this astronomical boost to their celebrations can take solace in the fact we will be compensated with an even rarer event: a month with no full moon.After New Year's Day's full moon, Australia will experience a blue moon on January 30, followed by no full moon at all in February. We will then have a second blue moon in March, coming on March 30 after a first full moon on March 1.

The last blue moon occurred in Australia in 2007, but the last time February had no full moon was 1991. It is not due to occur again until 2018.
