Exactly.
On December 21st, winter solstice in the North, it's 24 hours darkness at the North pole.
On the same day it's the summer solstice in the southern hemisphere. Ushuaia, the world's most southern city is 10,000 miles from the north pole. It gets 17 hours of daylight. Pretty much what we get here at the peak of summer. Sunset is 22.11, which is later than we have in the NE of England. For us here at that time of year it doesn't properly get dark until nearly 11 and even then the sky still looks light in the distance. It's not a proper darkness but a twilight. Then by about 3.30am for us the sky starts lightening in the east as the sun rises.
So in Ushuaia they will have similar conditions to us. They're 54° south, we're 55° north.
So how can they get 17+ hours daylight 10,000 miles away from the north pole, yet people in darkness for 24 hours don't notice a light source shining up (but not illuminating the area around it). It's bright enough to light a place for 17 hours a day 10,000 miles away but gives off nothing locally.
@Nukehasslefan what are your thoughts on this?
