The event is incredibly dramatic as the one location on Earth that does not turn as a function of daily rotation approaches the planet's divisor separating the light and dark hemispheres-

It is presently at its coldest at the South pole comparable to a location prior to sunrise is generally cold before it becomes exposed to solar radiation after the Sun comes into view as a function of daily rotation. The separate surface rotation as a
function of the orbital motion of the planet has the same effect by hemispheres insofar as the South pole does not rotate as a function of daily rotation yet has a single day/night cycle with the coldest period presently experienced at the station in
Antarctica-

The planet does not tilt towards and away from the central Sun, the planet has two distinct surface rotations acting in combination and it is time for 21st century people to recognise the fact that when daily rotation and all its effects are subtracted,
the entire surface of the planet turns once and parallel to the orbital plane arising from the planet's orbital motion alone.
Once again, the North/South poles, where daily rotation velocity is zero, experience a single day/night cycle per year/orbit of the Sun. This rotation is extended on to the entire surface using the expanding and contracting surface areas (with the North/
South poles at their centre) where the Sun remains in view and out of sight with those areas currently contracting towards the September Equinox
