  • Dawn at South Pole

    The one and only sunrise is approaching at the South Pole on the September Equinox as the South Polar latitude turns parallel to the orbital plane and into the light hemisphere of the Earth-

    I have noticed over the years that the light of the reflected moon is altogether different than the dawn light but this is another discussion in itself.

    The beauty and truth of this is that when daily rotation and all its effects are subtracted, the entire surface of the Earth still turns once to the Sun each year and parallel to the orbital plane as a function of the orbital motion of the planet.

    I personally find it unfair to ask people to follow technical matters that can be exceptionally difficult to perceive regardless of their accuracy and that includes the experiences here where dawn occurs a month or so before actual sunrise at the South
    Pole latitude on the September Equinox-

    With familiarity the whole spectacle becomes easier to appreciate as it involves two distinct rotations in isolation and in combination rather than contorting imaging to make it solely an issue of a 'tilting/tilted' Earth or worse (a pivoting light/half
    hemisphere of the Earth).

    Two weeks before sunrise at the South Pole and orbital dawn is well established there before the South Pole turns into the light hemisphere of the Earth-

    There never was a need to shove this down people's throat yet it happens every 6 months at alternative locations with the North Pole turning into the dark hemisphere of the Earth for 6 months.
