SUMMARY

The Sun sets at 71°11' latitude on July 27, with the first touch of the horizon occurring at midnight on August 27/28. This discussion highlights the importance of precise geographical coordinates in determining sunset times, particularly in polar regions. Users can utilize various software tools to calculate solar positions, although specific programs were not detailed in the conversation.

PREREQUISITES
  • Understanding of solar position calculations
  • Familiarity with geographical coordinates
  • Knowledge of seasonal solar patterns
  • Basic skills in using astronomical software tools
NEXT STEPS
  • Research solar position calculation tools like Stellarium or SolarCalc
  • Learn about the effects of latitude on sunset times
  • Explore the concept of the Arctic Circle and its implications on daylight
  • Investigate the mathematical models used for solar position algorithms
USEFUL FOR

Astronomers, outdoor enthusiasts, photographers, and anyone interested in solar phenomena and their timing in polar regions.

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:

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 :wink:

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

I owe you a beer.
