Hello Adstar - welcome.

Not quite sure what you mean by your question.  If you mean the most southerly place the sun is directly overhead - then it is the tropic of capricorn.  The two tropics, cancer in the north and capricorn in the south, are defined as the circles furthest from the equator where the sun at its zenith on the solstice is directly over head.  Nowhere north of t of cancer or south of t of capricorn is the sun straight up on any day of the year

As you can see from any globe the tropic of Capriciorn runs  about 2/3 the way up Australia the southern tip of Madagascar and the northern edge of South Africa in Africa and the northern edge of Argentina in South America.

I shink Aswan is north border - 2405'20"N
Then south border - 2405'20"S

Aswan is close to the tropic of cancer - but not exact.  In fact I shouldnt say exact - the topics can vary position by a fair portion of an arcminute every year

Here is an interesting app I found a while ago.

Daylight Calculator.  Put in the latitude, and it gives a nice graph of the number of hours in the day.

I know it is a slightly different question, but related.

Simplified - i thought that might be where you were getting it from.   ;D

I read a critique of that experiment, it implied that the results might have been severely manipulated by modern sources to bring the conclusion into line with modern measurement techniques.  Will see if I can dig out from memory where it was.
