This is going to be a Northern hemisphere object. :(

Well, that's not fair. I am therefore going to sue the International Astronomical Union. And organize a massive strike by astronomers.

I know we've got a history of demanding first but I am sure a deal can be worked out before we go so far as a strike. The south's got Omega Centauri, 47Tuc, the Coal Sack and the Southern Cross so maybe we can give them a comet. Hang on, the cross got nicked by that yellow convict colony so scratch that one, we'll put the Jewel Box in it's place. We still win I hope. :/

Allow me to ask seriously ignant questions for a moment...

The comet is in cancer at the moment. But the thing is comets move, and will likely reach max visibility a year from now. Is it unpossible that it'll be viewable by us right-way-up folk?

The comet's path must be calculated first. I think they need to estimate (measure) its position at three points in space (although it may be as few as two) to fit the movement of the comet to it's particular ellipse. With additional points becoming available, the path predictions can be refined. From there on it should be straight forward to tell where it will turn up in the near future. It is quite possible that this one could end up below our horizon at night, but if it's bright enough to be visible while the sun is up, we may catch a be glimpse of it yet. AFAIK comets in near proximity to the sun will at least be visible during sunset/ sunrise, so if you can see the sun setting or rising, you should see the comet too. If its bright.

We were spoilt by McNaught, and I'm happy to kick the bucket knowing that I've seen a spectacular comet during my lifetime. But a second will surely be a wonderful bonus!

ETA: This animation shows the comet approaching from the "top" (north?) of the planetary "disc" and leaving again on the "bottom" side ... hopefully that should afford each hemisphere a chance to gawk. :/Comet C/2012 SI (ISON), Close Approach 26 Dec 2013 - (expand the video info field - worth a read.)

According to the information at that YouTube video, both hemispheres will get excellent views, although the northern hemisphere's will be the best. It also says the comet was discovered by Russian amateurs Vitali Nevski and Artyom Novichonok of the International Scientific Optical Network (ISON).

So can we start calling it comet Nevski-Novichonok now instead of that unwieldy formal designation?
