Default Polar astronomy revisited

The animation is notable for a number of reasons however , in this case, it is applied to observing at the Antarctic station during polar twilight for about 6 weeks after the March solstice and polar sunset.

At habitable latitudes, twilight lasts for a short period each day but as polar twilight is from an entirely different rotational cause and within context of a single sunrise/sunset each year at the North and South poles, the extended polar twilight offers opportunities to observe planetary motions uninterrupted for long periods (weather permitting) at the South pole station.

This is just a normal consideration of astronomical methods made possible by human habitation and research in Antarctica, something that wouldn't have occurred to the original Sun centered astronomers. In a little over 2 weeks, the following event will happen at the South pole for the one and only time this year and that should be the point of departure for discussing everything else -
