Once every month, the moon moves in between the sun and the earth and casts a shadow; but most of the time the position of the moon's orbit relative to the earth's means that this shadow misses us entirely.
This morning, however, we got to see the first solar eclipse of 2009 (and the best one that will be visible from South Africa for several years). The eclipse was only partial, with a maximum coverage of about 65% visible from Cape Town just after 8am.
Of course, a partial eclipse doesn't mean darkness by any means, despite what you see in the photo - the sky was actually perfectly blue, but Paul took the photo using a very high shutter speed and small aperture. Everything seemed to take on a slightly paler, softer look, though, almost as though the earth and sky were covered with gauze.
And don't worry, no eyes were harmed in the making of this photo. ;-)
Update: Take a look at Justin Hartman's awesome shot of the eclipse. I love the colours of the swirling clouds - that'd look good on a canvas, don't you think?
