Question about Mcnaught...

Does anyone know where there is an explanation for why it swapped for northern to southern hemispere viewing? I know it is probably simple and just a matter of geometry. But I would like to understand the full reason.

thanks

Comet McNaught has an orbit that is highly tilted compared to the earth's orbit. Once it passed far enough south of the earth's orbit it moved into a better position for viewing from the southern hemisphere. Here is link that shows the orbit, scroll down the page a bit and check out the quicktime animation that shows the comet orbit compared to the rest of the solar system.
