What is a hybrid solar eclipse, the rare celestial event being witnessed today?

Hybrid solar eclipses are eclipses that shift from annular eclipses to total eclipses due to the Earth's curve. A total eclipse is one where the Moon fully obscures the Sun, whereas, in an annular eclipse, the Moon cannot cover the Sun completely, leaving a ring of light. The rare hybrid eclipse is visible today in Australia, Indonesia and East Timor.
