In all cases the Equinox is described as an event where all places on Earth experience equal amounts of daylight and darkness, however, this is never the case in a dramatic way -
https://www.timeanddate.com/sun/antarctica/south-pole I can't find a website that has the time and date for North polar sunrise but what is important is that Polar dawn breaks into Polar sunrise at 90 degrees North around the Equinox. A lot goes on around the Earth's orbital plane and how to interpret observations looking inwards to the central Sun whether the meta observation based on orbital motion or indeed the fact that the Earth faces the same direction in space causing it turn change that orientation to the Sun. The Earth's hemispheres neither tilt towards or away from the Sun over the coming days,weeks and months.The basic fact is an isolation of the polar day/night cycle by rotational cause and ultimately the fact that in the absence of daily rotation and all its effects, the entire surface of the planet turns to the Sun with its rotational period coincident with an orbital period. The people of this planet need something good for a change to focus on rather than just rabid pronouncements of those who have no real interest in astronomy, space and the conditions that make life possible whether in an academic or political setting. |

The last day where the Sun is in view before it turns out of sight for 6 months as the Earth continues its journey through space and around the Sun and nice to see such a clear polar evening before the Sun sets for the one and only time this year. In a world full of anxiety and crude people in politics and elsewhere, these observations bring a gentleness to those who look for the productive and creative side of life when things seem cruel and dour. |

Such a beautiful image of the full moon presently where the location of the South pole is roughly 90 degrees to the full moon where the polar latitude lies on the circle of illumination while the Moon, while distant, is midway in its journey across the fully darkened face of the Earth. |
