Crescent sun eclipse gives Australians rare visual treat

A solar eclipse that occurs on average only once every 73 years may be perfectly witnessed only by penguins in Antarctica, while watchers in Australia had a shot at seeing the sun as a “super-fat banana”.

The crescent sun, an annular eclipse meaning that the moon is too far away to completely block out the sun, instead creating a perfect ‘ring of fire’ could be witnessed in Perth, Australia, from 05:00 GMT on April 29. Such eclipses are relatively common, with about four every five years. The last occurred in May 2013.

What makes this eclipse – the first of 2014 - unusual is that it is non-central, meaning that the center of the Moon’s shadow will not fall on Earth, instead passing above the Southern Hemisphere sky.

Of 3,956 annular eclipses calculated to have happened or scheduled to happen between 2,000 BC and 3,000 AD only 68, or 1.7 percent, are non-central annular eclipses. This is only the third such event since the 17th century.

As most of the shadow was set to miss Earth – the perfect spot to watch the eclipse at its most symmetrical would have been above the planet . The only place where the “ring of fire”, or annulus, can be seen at all is in Antarctica. The spot is half way between the Dumont d’Urville and Concordia stations – located 1,100 km apart – meaning that in all likelihood no human was able to witness the unusual phenomenon.

"This is a thoroughly bizarre eclipse," said a statement from Bob Berman, an astronomer with the Slooh Space Camera, which broadcasts astral events online.

“As we will watch in real time as the inky black hemisphere of the moon partially obscures the sun, the greatest thrill might be an awareness of what's occurring — unseen by any human — in a tiny region of Antarctica."


For sentient observers, due to the imperfect angle of observation the phenomenon wouldn't "look any different from a normal, partial eclipse," Stephen Hughes told Australian Associated Press. A partial eclipse occurs when the Sun and the Moon do not fully align, so that the latter blocks out only a chunk of the former.

About half the Sun was covered when the eclipse passed Sydney, and more than two thirds over Melbourne.

"Melbourne will be quite a bit better than Sydney ... a super-fat banana,"Hughes said before the event.

The eclipse could also be perceived in southern Indonesian islands.

NASA published an interactive map that allowed Australasian residents to see when the eclipse passed through their area, but as usual, amateur sky-watchers were instructed to avoid looking at the Sun without protective equipment.

The real visual treat comes when you look down at the shadows of the trees.

What were little round dots of light, on the places where light found its way through the leaves, are now little crescents of light.

I was walking on a tree shaded country road, during an eclipse in my country, and the road was transformed in a myriad of little brilliant crescents of light...

Just magical...
