December 21 is the northern winter solstice. Here in Selfoss sunrise was at 11:14 and sunset at 15:29 and the sun is just 2.7° over the horizon at midday.

In the last couple of days we have had temperatures below zero. The days are getting shorter and the river Ölfusá has begun to freeze. This photo is taken around 5 o’clock this afternoon and as you can see the sun is setting.
