As I mentioned in an earlier post, we are hoping to go to the far North in early December because the aurora will be at its peak, and so is Comet ISON (supposedly).
Looks like ISON will be a bust: http://www.skyandtelescope.com/news/Comet-ISON-Recovered-and-Not-Looking-Good-219432571.html

In the lightcurve prediction graph presented by Scarmato, Morales and Gary, their green line corresponds to typical "new" comet behavior. Note that this suggests the comet's brightness barely ever breaks the naked-eye barrier, even at perihelion!
Further, if one accepts anything like the green line's absolute magnitude of +9.73 for the comet, then ISON has no chance of surviving its perihelion, based on my paper "Post-Perihelion Survival of Comets with Small q" (International Comet Quarterly, Vol. 13, No. 3, July 1991).
Bruce Gary lives near me, but we've never met. I sleep when he's awake. :)
