It will be the first total solar eclipse in over 10 years, and thousands of people have gathered in northern Australia to see the rare phenomenon due to take place at dawn on Wednesday.
However, forecast cloudy weather may obscure the view for budding skygazers.
“We’ve just driven 3,000 kilometers for this weather to see the eclipse. You can’t pick your weather, can you? You can pick your friends,” said one man, standing in the rain.
A cloudy sky is not a foregone conclusion, according Jay Pasachoff, an astronomy professor at Williams College, Massachusetts.
“People have looked back at clouds statistics from weather satellites going back 20 years, so we know it’s 50-50 or 60-40 chance. We’re still hoping for clear weather,” he said.
There will not be another chance to see what happens when the moon passes between the Sun and Earth until March 2015.
