This is an important test as it allows us to get past the simple astronomical claims of elevation and azimuth. Sure, we did predict the 24hr Sun at Union Glacier including the exact angles of elevations; however since there is only one sky, globers will lie and say that accurate Flat Earth predictions are actually globe predictions. Only wrong predictions will they accept. This is one of the reasons we know they are disingenuous.
Having that said, that is why this test is so valuable as it is harder for them to strawman as we are not using any astronomical claims. We are simply seeing how a flat geometric surface causes three spots to appear when looking in 1st person from two different locations, United States and Union Glacier. We also zoom out to show how the sun physically looks at the point of dome refraction. Very simple, no funny business, anyone who knows basic 3D modeling can actually replicate this in free software such as Blender to confirm that there is no hidden globe math in this very simple planar geometric observation.
These photos of the sunspots have been verified by Dave McKeegan. I did not conduct this observation myself yet it still confirmed the hypothesis of the Flat Earth model. This is the pinnacle of scientific achievement. https://www.youtube.com/watch?v=eYm6q8JY7Hk&t=827s
Remember that we made sure to make this model free for anyone so that there would be no limits to education and no excuse for not understanding how the 24hr Sun works on our Flat Earth https://firmamenttrackers.com/
