The explanations as to why this does not prove the Earth is flat is great. I am not a flat Earther (I very much believe it to be roughly spherical) but I didn't know something like this could be explained by "atmospheric refraction" It gives me even more respect for astronomers and physicists that they are able to account for factors like this when doing their calculations.
