Night falling is not usually remarkable, until you haven’t seen it for 10 days. My app had predicted that today would be the first day we saw anything which looked like night, and it was right. We passed out of civil twilight (technically into nautical twilight when the sky is still not dark), so you’d need street lights to be able to see.
The above pic was taken at local midnight, the ship’s light and the street light is the brightest light there is. The place is not marked on Google maps, so I’m not sure where it is. (61° 3′ 13.62″, 4° 58′ 32.04″ looking southish.) This is still north of where we were in Shetland, but by the morning we got to Bergen and latitudes we had covered in Shetland.
Here are also some views of the journey to Bergen.
