Tell me who paints the sky?

Things i must see before i die. The southern lights and the midnight sun!

The aurora borealis can be seen various places in the world, within the polar circle. It is often described as dancing lights.
The northern light has always had something magic about it, something mysterious. It is a beautiful occurrence and it looks like something straight out of a fairytale.


The aurora is a common occurrence in the Poles. It is occasionally seen in temperate latitudes, when a strong magnetic storm temporarily expands the auroral oval. Large magnetic storms are most common during the peak of the eleven-year sunspot cycle or during the three years after that peak.[citation needed] However, within the auroral zone the likelihood of an aurora occurring depends mostly on the slant of IMF lines (known as Bz), being greater with southward slants.

And, the mignight sun!



The sun really never goes down at this time of year. This shot was taken at midnight. Imagine all the people there, kids play until midnight! Wow. Great.

A little research at wikipedia:
The midnight sun is a phenomenon occurring in latitudes north and nearby to the south of the Arctic Circle, and south and nearby to the north of the Antarctic Circle where the sun remains visible at the local midnight. Given fair weather, the sun is visible for a continuous 24 hours, mostly north of the Arctic Circle and south of the Antarctic Circle. The number of days per year with potential midnight sun increases the further poleward one goes.

There are no permanent human settlements south of the Antarctic Circle, so the countries and territories whose populations experience it are limited to the ones crossed by the Arctic Circle, i.e. Canada, united states of America (Alaska), Denmark (Greenland), Norway, Sweden, Finland, Russia, and extremities of Iceland. A quarter of Finland's territory lies north of the Arctic Circle and at the country's northernmost point the sun does not set for 73 days during summer. In Svalbard, Norway, the northernmost inhabited region of Europe, there is no sunset from approximately 19 April to 23 August. The extreme sites are the poles where the sun can be continuously visible for a half year.

The opposite phenomenon, polar light, occurs in winter when the sun stays below the horizon throughout the day.
