Eclipse Shirt 2009.

Of course , everyone is concerned about what to wear to a solar eclipse . This is a great example though, especially for the first eclipse of the International Year of Astronomy 2009 . In the picture, recorded during the January 26 solar eclipse from the grounds of the South African Astronomical Observatory at Cape Town, repeated images of the eclipse adorn a well-chosen shirt. The effect is familiar to eclipse enthusiasts as small gaps, commonly between leaves on trees , act as pinhole cameras to generate multiple recognizable images of the eclipse. From the Cape Town perspective, the solar eclipse was a partial one, with a maximum of about 65% of the Sun covered. But along a track extending across the Indian Ocean and western Indonesia the eclipse became annular, the solar disk briefly appearing as a fiery ring around the silhouetted Moon.
