When does the Sun sets down at 71°11'

[Borek]

Bear with me, I am not even sure if I know how to properly word the question.

Few days ago there was summer solstice - that means Sun was visible all day north of arctic circle. My question is - when will the Sun set down at 71°11'? Now, Sun is not a point, so perhaps better question is - when will the Sun touch the horizon for the first time at 71°11'?

I know there are tons of shareware/freeware programs that can calculate such things, I remember using one of them back in nineties, but I don't have enough time right now to search, download, install and learn enough user interface to check. Hopefully someone has right tools at hand and can answer. In return I can calculate pH of any mixture

At midnight of August 27/8, it just touches the horizon - two days later it is completely below.

Judging from the screenshot you mean July, not August

Many thanks, that's exactly information I was looking for. And I must admit end of July is a good news

I owe you a beer.
