The tropic of Capricorn is the southernmost point the sun appears directly vertical overhead. You are claiming it can "appear" further than this due to the tilt, when the tilt itself is responsible for the tropic of Capricorn and appearance of the sun's position in the first place. You are claiming the phenomenon that causes the tropics to appear where they do, the tilt, is also causing it to appear in a different location than the tropic by definition defines? I do not follow this logic, nor do I agree with its conclusion.
Clearly, you are misunderstanding my assertion. I'm not claiming for a second that the Tropic moves! The probably is some variability, but essentially it is a fixed line due to the earth's tilt. What I am addressing is the
appearance that the sun is more southerly.
Where I live in Canada, in the mornings from about late April to mid-September, the sun first appears at a point north of due east; in other words, far north of the Tropic of Cancer. It is not "directly above" that point, but it
appears to be, given the tilt of the earth. Similarly, in the southern hemisphere in their summer, the morning sun
appears at a point south of due east, though it is not directly above that point. At that time it would be directly above somewhere in the Southeastern Pacific, perhaps off the coast of Chile, but its nadir point (the point on the earth's surface at which the sun is directly overhead) is never further south than the Tropic of Capricorn.
The appearance of the sun as further north/south of the relevant Tropic line is due to the tilt of the roughly-spherical earth. I chose to focus on the Tropic of Capricorn because most of the maps and arguments place the centre of the earth at the north pole. Again, in that model of a flat earth, the sun can
never even appear to be more southerly than the Tropic of Capricorn. The model simply doesn't allow for that possibility. From any point south of the Tropic of Capricorn, the sun must
always appear to be further north... morning, noon, and evening, every day of the year. That's why the date of the photo is irrelevant.
This is basic geography; grade school level. Even if you finally reject my assertion, please at least do enough homework to understand it.
