In a nutshell: regardless of where you are on the planet, this comet - when at its brightest - in March 2013 will be predominantly an early evening object at low elevation in the fading dusk, first for the southern, then for the northern hemisphere; there are also occasional (and usually even worse) morning visibility windows.

To get it all, one should be deep in the Southern hemisphere from late Feb. til about March 9, then move swiftly to a mid- to high-northern latitude. Low northern latitudes in the March 5 ... 15 timeframe (around expected greatest brilliance) are also a possibility. There is no place on this planet so see the comet in a dark sky around its greatest brightness as the solar elongation is just too small then.

C/N: Sun depression 6°, N/A: Sun depression 12°, dark: Sun below -18°
