Fingers crossed! But it will be a northern object if it does survive the passage inwards & perform well, despite what the article says.

We have it low in the north in the evening until around June 2012 when we lose it to daylight. We get it back briefly around the start of October, very low in the ENE in morning skies as it dives sunwards. If it survives & gets very bright, we might be able to see the comet in daylight skies, near the Sun. After perihelion, the comet moves back into dark skies for northerners, but for us the comet & any spectacular tail that might develop rise after the Sun, in daylight. In far northern Australia, it might be possible to see the outer tail making a low angle with the horizon, depending how big and bright the tail might be.

In early Feb 2014 it will start to broach our northern horizon in evening skies, but at a predicted mag 9 or so. It never gets very high and we lose it to daylight again around May, when it would be quite a dim object.

Also, it's not a sungrazer - it goes quite close to the Sun but not as close as sungrazers do. Some people are calling it a 'sunskirter'. So it's not like Comet Lovejoy that basically had to survive a passage through the solar atmosphere at perihelion.

Worth watching, but if it performs well you'll have to go a long way north to see it!
