Where are the Polar Nights?

The Arctic Circle sits at 66°33’N. At this point of latitude the sun doesn’t rise on the day of the winter solstice (and doesn’t set at the summer solstice), though, as the sun is hovering just below the horizon, the Arctic Circle never goes completely dark – there’s always a bit of dusky twilight. The further north into the Arctic Circle you go, the longer the periods of winter darkness.
