In the winter the sun hides itself until about 08.30 and decides it has had enough only to leave the poor Scandinavian people to see that it has hidden itself again by 16.00. This leads to a very dark and cold winter.
The summer on the other hand is quite opposite from winter: perpetual darkness turns to perpetual lightness. It never actually gets dark. Sitting in a dark room looking to the wil' blue yonder means being able to see the outline of the trees set against a dark blue atmosphere. Looking in the direction of Sun's last light reveal a lightened glow. By 03.00 it noticeably gets light, by 04.00 one has no problem seeing and by 05.00 if my shade isn't down I get the sun (I get the morning sun directly through my window and to my sleeping figure). It gets noticeably dark by 22.30.
This picture was taken at exactly 22.56 from my desk looking out to the sky. It is still noticeably light at 23.00!!
This one was taken at 02.42. Toward the far left of the tree line is a bit of a dip, the sun comes up right about here (obviously you can see that it is lighter there) and to the right you can see the moon.
