To have a summer day longer than 12 hours in Australia, South Africa or South of Argentina, even Uruguay (I was born close to Uruguay), the Sun's light must hit the exactly same point in the ground for more than 12 consecutive hours, changing angle of incidence, of course.
Considering the FE Sun circles over the FE disc once every 24 hours, then it must cover more than 180 degrees of the southern FE land at any specific time during southern summer.
Can any FEr please, draw a specific geometric shape over the FE map, even crude, showing this coverage ?Additional text:
The big problems for FE is the southern hemisphere, always, this is why both, FEr or REr, we need to stress any issue in attempt to clarify any doubts through the scientific way. There are plenty of FE issues there, direction of rotation and visibility of the stars, lands dimensions and ocean distances between them, times of flight, Sun presenting itself 360° all around during summer (the killer issue), etc.
I was raised watching the Crux Constellation every night, rotating in the sky, stars Acrux (the 12th brightest star in the sky), Alpha Crucis magnitude 0.77. It is on declination -63°, due the Earth's curvature it can not be seem north of latitude 27°N. It was my first telescope observation at 6 yrs old, we didn't have so much light pollution at that time, skies were really black and clean. The Crux is a circumpolar constellation at 34°S, it means it is visible all year round in the south, and its position is the opposite of Cassiopeia in the Northern sky. There is an image of the Crux on the rocks of Machu Picchu in Peru, the Inca knew it as Chakana. It is also presented on the Australian and Brazilian flag, its name was used as Brazilian currency denomination for quite some time. There is a trick to use the Crux to exactly locate the South Pole, it was an important navigation tool before GPS, as the North Star was for the northern hemisphere.
