I want to be a tourist in Sweden some day... what a lovely country. Sigh. Oh, also a lovely sun pillar.

Well, as a Swede with no interest whatsoever in winter sports, I don't exactly know, but I have to agree that this looks tourist-y. Those houses look like the sort of cottages that winter sport freaks might hire for a couple of weeks in the winter.

Östersund, where this picture was taken, is not all that far from Åre, one of the real tourist traps in Sweden.

In this case, the ice crystals do not fall from high level clouds. They seem to be a part of the thin ice fog forming at sunset with rapidly falling air temperatures.

Yes, these have been featured in several APODs: http://apod.nasa.gov/apod/ap020902.html, http://apod.nasa.gov/apod/ap090112.html.

Image A Sun Pillar Over Sweden

Explanation: Have you ever seen a sun pillar? When the air is cold and the Sun is rising or setting, falling ice crystals can reflect sunlight and create an unusual column of light. Ice sometimes forms flat, six-sided shaped crystals as it falls from high-level clouds. Air resistance causes these crystals to lie nearly flat much of the time as they flutter to the ground. Sunlight reflects off crystals that are properly aligned, creating the sun-pillar effect. In the above picture taken last week, a sun-pillar reflects light from a Sun setting over Östersund, Sweden.
