I don't need to go there, it was in the documentary: "Antarctica A Year On Ice"
At Antarctica facing a camera North, the sun doesn't go past the front of the camera (or in a "sideways on" fashion if not facing North) like it would in a flat earth model, instead in the documentary it goes 360 degrees around the camera - which is impossible on a flat earth, because the sun would be overlapping the ice shelf by thousands of miles.
Granted, I have no clue which way the camera was facing in the documentary, but this doesn't affect whether the sun would pass "across" you (FET) or go around you 360 degrees (RET).
For the sun to be going 360 degrees around AND us being on a flat disc, we would be living in some sort of figure of 8.
Or, face the camera South... now you should
never see the sun in front of you on a flat earth, it is above the horizon every day for four months so its not like there's no time to check it.
You can see the sun going past the camera when the camera is facing South, oops!
Flat earth busted, that easily.
