In a few days there is this wonderful dawn at the North pole that happens once each year as the Sun comes into view after being absent for 6 months while at the other pole the Sun vanishes from sight -

I am not interested in the utter hatred for the rotational cause of polar sunrise, what I am interested in is the teamwork necessary to explain the observation by using lessons learned from daily rotation and the appearance of the Sun each day.

I went out early this morning and watched the Sun come into view down by sea level where neolithic astronomers once marked the Equinox and that reward is something money cannot buy. I honor these ancient people by adding to their recognition of orbital points by taking account of polar dawn and its cause arising from the motion of the Earth around the Sun and even if nobody else cares to look at the time lapse at the South pole in the YouTube website, it will always happen twice a year at either poles.
