sunrise and set months in south pole?

Answer 1

At the poles, the Sun does not really rise or set. For the course of a single day, it maintains the same altitude above (or below) the horizon. On the equinoxes (like this past Sept 21) the SUn is half above and half below the horizon for the day. Over the next few days after the equinox, the Sun at the South Pole climbs a little higher each day. Around December 21st (the solstice) it reaches a maximum altitude of 23.5 degrees. After that it begins to descend, crossing the horizon around March 21st.

Answer 2

At the very South and North Poles there is one day and one night each year. The sun slowly spirals up, and then down. Of course when the sun goes below the horizon it isn't instanly dark. So there is a month or so of twilight. So maybe 4 months of quite dark. During this time the moon is up for 2 weeks out of every 4, and thus it isn't as dark either.

Much of the coast of Antarctica is near the Antarctic circle. So there is a shorter period around mid winter when the sun does not rise.

Answer 3
