To SMEaton:
Please, google more data and images concerning the MIDNIGHt SUN.

How do you explain that the time is midnight and the sky is clearly that of the familiar night meanwhile the Sun is still shining above the horizon?
Why is the skylight absent while the Sun is still somewhat high above the horizon?
Why is there a direct solar light while there is no daylight spread in the sky?
How is it a real night in a clear sky and at the same time the Sun is still sending its light while seen distant tens of minutes from the horizon (the supposedly sunset horizon)?
Do you agree on this statement:
"Were the Sun as a luminous body the origin of the skylight, this skylight shoud not be absent at all where the Sun itself is still shining above the horizon"?.
