A supermoon has shone above [url=http://maps.google.com/maps?ll=-35.308,149.1245&spn=10.0,10.0&q=-35.308,149.1245 %28australia%29&t=h]Australia[/url], creating an impressive view in the early evening sky on Sunday and bringing a king tide.

“Everyone thinks the orbit of the Moon is a perfect circle – well it’s actually slightly elongated,” he said.
“Because of this, at certain times the Moon will appear larger, and sometimes appear further away.
“A supermoon is when a full moon occurs when the Moon is at its closest approach to the Earth.”
Mr Tucker says the most impressive view was at dusk when the Moon was close to the horizon.
He says that is mostly due to an optical illusion.
“It will actually physically be a little bit bigger, because it’s closer … (it) will appear about 10 per cent larger,” he said.
“But the Moon always appears bigger on the horizon when it rises.Full story and video au.news.yahoo
