Off to the Arctic Circle

I'm off to the Arctic Circle this weekend.  Specifically, I'm on the way to Tromsø, Norway.

The Arctic Circle is about 16,000 km (9,900 miles).  About 4% of the Earth's surface lies north of the Circle.  The Circle crosses Norway, Sweden, Finland, Greenland (Denmark), Iceland, Russia, Canada, and the USA.  Due to the severe cold, only around four million people live there.

The Arctic Circle isn't fixed.  The latitude depends on the axial tilt of the planet.  The Circle is drifting north about 15 metres (49 feet) per year.

At this time of year there will be very little daylight, maybe only five or six hours per day.  The reason for going this weekend is to try to see the Northern Lights.  Fingers crossed for good weather.
