According to organizers of the trip, Spitsbergen Island offers the best land-based weather prospects for the eclipse. Average cloud cover at Longyearbyen is at 56 percent, with a very low probability of overcast skies. Additionally, the high latitude of this eclipse means that viewers in Svalbard may get a special treat: a glimpse of the aurora, or possibly ice halos, during totality.
Organizers note that these extras are indeed long shots, but are possible should the magnetosphere be particularly active on the hour, or if a thin cirrus overcast is present, containing just the right orientation of ice crystals. Regardless, this is one of the two optimal destinations on the planet for "totality" viewing, and an event that you’ll remember long after it’s over.
