Hi atti: Most of the time, I am also dissapointed when I get a link = URL instead of an opinion. Opinions are much easier to rebut (and ask for more details) and I am suspicious that the united laws of the mainstream scientists are at least slightly flawed, if not a mess. Often the link is time consuming, but not very helpful.
The closest I came to experiencing the midnight sun was from Fort St, James, BC, Canada, in June, about midnight. I noted that the sky was slightly twilight due North. At that time there were no villages a few miles North of Fort St. James, so I comcluded (perhaps wrongly) that I was seeing genuine twilight.
The point is, if you are just outside the Arctic Circle about June 21, the sun will set at about 358 degrees near midnight and rise again a few minutes later at about 2 degrees. A few miles farther North the sun will touch the Northern horizon without setting and come back up.
On June 21 about midnight. A thousand miles farther North the sun will not set or even kiss the horizon in May, June, July and most of August. Neil
