What latitude would suit observers? McNaught was very much for our Southern Hemisphere friends.

I took a quick look at the open front page of your favorite comet forum, Gladstoner, and seemed to see several people congratulating an Anatoli Nevski for the discovery. Will this be Comet Nevski, then?
Got to be a good connection to be made to Alexander Nevski, somehow, if so. "Oh, noble yeoman, thy tail shineth so bright..."  -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Ok... STARRY NIGHT is now updating with the orbital elements for the comet, so here are some screengrabs. Use these as a guide to WHERE it will be, and what will be around it. Do NOT take these tail lengths as accurate. Sky rendered for my viewing location in Kendal, Cumbria, UK. Your local viewing circumstances will differ, but if you live in the north this will give you a rough guide...
Basically, pray for a clear sky where you live on Nov 29th...!!! November 16th before dawn...
November 22nd before dawn...
November 28th before dawn... (McNaught-like tail fan visible before dawn?)
Nov 29th before sunset...
Nov 29th after sunset...
December 2nd after sunset...
Christmas Eve after sunset...

Definitely a time of year where Seattle has tons of clear weather.

This comet makes a very close approach to Mars around October 2nd, 2013, about 0.07 AU. It has the potential for some great photos from MSL or Opportunity! JPL's HORIZONS is predicting a visual magnitude of 2 as seen from Mars at closest approach.

That would be an amazing first! Let's hope for clear skies on two planets!

I would guess that Oppy would have little chance for observing ISON as we would be well on our way toward winter solstice. Curiosity would have a better chance I'd expect? (Assuming reality roughly follows hopes and expectations of course.)
Would a pair of observations of ISON (any comet really) from a known location on mars be notably more enlightening regarding the comet (orbit or visual attributes) than 'ordinary' observations from earth? -- Pertinax |

I think observing from two planets would add information, especially on 3D tail structure. Maybe someone will make an interplanetary anaglyph. |
