As the sun rotates above the flat earth, horizontally, daily on its' northern journey , over the north pole, its' rotation is smaller and it's location is north of the equator. it stays in sight at the north pole for 3 months because its' position is northerly and the star cloud focuses to the north also.
when the sun is over the south pole there is a large magnifying glass which is above the star cloud which keeps the sun in sight at the south pole for 3 months, because the sun rotates clockwise and its' most southern location is above the tropic of capricorn and therefore only a magnification of it could keep in sight for 3 months.
the star cloud also effects our view of the sun. the star cloud is the cloud which has holes in it through which sun light above it causes these holes to look like stars [ or may they be orbs themselves within this cloud]
rotate a flashlight with your wrist against a wall and see the light going around. now put a large magnifying glass in front of the flashlight. you will see the light still spinning around and you will also see a light in the middle of the rotating light, because of the magnifying glass.
the sun spins around the same way at the north and south poles and it moves back and forth from north to south also, but when it is south, a magnifying glass of some celestial sort keeps it in view at the south pole becasue its' rotation is larger but still completed in 24 hours. the spinning star clouds angle and shape causes the prismed view of the sun.
this is also in harmony with the different moons also, 1/4 moon, 1/2 moon, full moon, shaded moon, etc.
