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![Wink :wink: :wink:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
