Gentlemen,

I want the answers to be restricted to the night of the midnight Sun for a specific night (of 21th of June , Summer Solstice) at a particular latitude that is: the Arctic Circle.

(1) How does the midnight Sun really appear?
(2) Do people see the stars and planets during the night of the midnight sun?
(3) Is the night of the midnight Sun real? In other words, is there a real darknees along the night of the midnight Sun or during any part of it?
(4) How long is the night of the midnight Sun?
(5) What about the behavior of the birds and animals at such a night?
(6) What about the auroras at the time of the midnight Sun?
An extra question:
(7) What about the colors at the time of the midnight Sun?
